= 20161007 Commissioning Plan = Priorities for test are in the order listed in the plan below. Highest Priority: Engineering; do any support for Hanshin or Randy in support of Hanshin. == Closed dome engineering for bad weather, or while stacking: == === Closed dome trajectories === Purpose: Exercise the system to find any problems with the upgrades recently done to TMCS and TCS. Procedure: * Send a trajectory from do_shuffle * Setup on trajectory, including moving all guide probes to position * Put one some light in the dome * Run all cameras. * Run pipelines for WFS * Make offsets on all guiders and ACAM. Repeat multiple times during the night as long as the weather does not allow you to open. == Twilight Tests == === start doing twilights with VIRUS with different tracker positions === Purpose: There is some interest in seeing what the long term illumination correction changes look like including what different track positions do to them. The script is "specialtwilight" in /home/mcs/astronomer/bin/. It takes a single argument which is the Observation number. Procedure: * Setup the guide camera for sky twilight (GC2, 0.1 sec, B filter) * When you hit the correct flux level (biased to a slight higher value, perhaps 5k) execute the specialtwilight script == On-sky engineering: == === Test Calibration of CWFS === Purpose: We want to calibrate the CWFS using DWFS8 on a geostationary satellite. '''NOTE: Due to the poor weather the emphasis should be on the Satellite calibrations so do several different satellites before moving on to the stars''' Procedure: * setup on a geostationary satellite on the IHMP position * get rough focus and confirm that GROC is ok * Retract ACAM * Open the PFIP shutter {{{ syscmd -P -v 'OpenShutter()' }}} * null out the offsets for X,Y,focus, theta, phi on DWFS8 * The X and Y prescribed corrections are between -1 and 1. * The Theta and Phi prescribed corrections are between -10 and 10. * The focus prescribed corrections are between -0.05 and 0.05. * save 15 images with DWFS8 ( use 3-4 sec exposures) * offset to CWFS (-5.5 in X) * null out the offsets in X and Y only. * save 15 images with CWFS (use 3-5 sec exposures) * move back to DWFS8 (+5.5 in X) * repeat the above steps 4 more times === Calibration of OWFS using either CWFS or DWFS8 === Purpose: We want to calibrate the OWFS using DWFS8 or CWFS (depending on what stage of the testing we are in, Feedback from Hanshin) on a sidereal trajectory at one of the following Az: '''a normal star for Az 180, 234, 292, 335, 0''' * setup on an 11 mag star on the IHMP * move all 4 guide probes to the correct RA and DEC positions from gstar or shuffle. * save probe positions in the RA log with /home/mcs/astronomer/caldwell/shoprobes * '''If the test is to use DWFS8 then skip this step otherwise offset telescope and probes by the amount to get to CWFS: {{{ syscmd -T 'offset_trajectory(dx_ang=-5.5, dy_ang=-1.0, adjust_probes="true")' }}}''' * move the guide probes so that the guide stars are well centered * guide with either GC1 or GC2 * get decent focus and then check and correct any GROC * Retract ACAM * Open the PFIP shutter {{{ syscmd -P -v 'OpenShutter()' }}} * null out the X, Y, Focus, Theta, Phi from DWFS8 * To make X or Y offsets you will need to: * open the loop on the guider * make your offset with the handpaddle * clear the fiducial * watch as new fiducials are set to see if it looks good * close the loop on the guider * To make the Theta and Phi offsets you will need to: * open the loop on the TTC * make your offset with the handpaddle * clear the fiducial * watch as new fiducials are set to see if it looks good * close the loop on the TTC * The X and Y prescribed corrections are between -1 and 1. * The Theta and Phi prescribed corrections are between -10 and 10. * The Focus prescribed correction is between -0.05 and 0.05 * make small offsets with the OWFS1 and OWFS2 to get the lenslet centered. {{{ To move the wfs probes: syscmd -T -v 'WFS1_offset_probe( dx_ang=1.0, dy_ang=0.0) ' syscmd -T -v 'WFS2_offset_probe( dx_ang=0.0, dy_ang=-0.5) ' The coordinates are in units of arcseconds. }}} * save probe positions in the RA log with /home/mcs/astronomer/caldwell/shoprobes * save at least 15 images (at the same time) with all cameras that are running: GC1, GC2, WFS1, WFS2, DWFS8, TT '''NOTE: This can be done one jove terminal as {{{startsaving}}} followed by {{{stopsaving}}}''' * wait 10 minutes * null out corrections on DWFS8 or CWFS * NOTE: if you need to make X and Y offsets you should probably do this with a trajectory offset with probes=true to keep the WFS1 and WFS2 well centered * e.g. {{{ syscmd -T 'offset_trajectory(dx_ang=0.0, dy_ang=-0.3, adjust_probes="true")' }}} * check GROC, make correction is required ( > 500 um correction) * null out corrections on DWFS8 or CWFS again if required * The X and Y prescribed corrections are between -1 and 1. * The Theta and Phi prescribed corrections are between -10 and 10. * The Focus prescribed correction is between -0.05 and 0.05 * save at least 15 images (at the same time) with all cameras that are running: GC1, GC2, WFS1, WFS2, DWFS8, TT * repeat the last 5 steps until the end of the track. * Close the PFIP shutter {{{ syscmd -P -v 'CloseShutter()' }}} Repeat test: choosing a new star at the next Az in the list: 180, 234, 292, 335, 0. === Determine focus offset between GC1/GC2 and DWFS8 === Purpose: We want to determine the focus difference between GC1 and DWFS8 and CG2 and DWFS8. The idea will be to set the position with DWFS8 and then do a focus curve with the GC. * select a trajectory with an 11 mag star and some stars reasonably bright for GC1 and GC2. * start guiding on GC1 or GC2 * pull out the ACAM and null out the offsets for DWFS8 * make sure GROC corrections are less than 250. null out corrections again if you did make a GROC correction. * stop taking images and stop the pipeline for the guide probe of interest, or both probes if you are using script10 * use fC on the guide probe of interest, e.g. {{{ fC -exp=5 -camera=Guider1 }}} '''However this is currently non-functional because of python/matlab limted''' * if you can't use fC then copy script10 from /home/mcs/astronomer to /data1/mcs/guider/YYYYMMDD/ and use this script to take data. * repeat this 2 more times with these same guide stars. * if you are using script10 measure the FWHM and determine minima and report that for each curve along with the probe position. * select another star with the probes in a different part of the annulus. === doing globular clusters with VIRUS === Purpose: We need to fill the IFU with lots of stars. Take a bright GC and move it to four different positions in the IFU array: 084, 085, 094 and 095. Procedure: * Select a bright globular cluster near the beginning of track (try to avoid the CCAS tower). * Using do_shuffle put the center of the GC in one of the IFUs 084, 085, 094 and 095. * What ever method is used to setup on the the cluster, save the IHMP clearly in the RA logs. * setup on the target * save an ACAM image to document the setup. * go through a series of dithers with 180 second exposure at each dither. * when done with this setup, setup on the next IFU. '''Note if required this test could be split over nights.''' * contact Karl that the test is complete. === Test offsetting from LRS2-B -> R using GC1 & ACAM as a function or rho angle === Purpose: We want to see if rho angle of the tracker matters for making good reproducible offsets from LRS2-B to LRS2-R. Procedure: * Setup on a Az = 0 star (not saturated so probably should use V=16) using GC1 and LRS2-B near the start of the track * Setup on one of the GC in nearly exactly the center of the GC field (record the pixel X and Y used) * Be sure to record the tracker positions including the rho angle * Using repeated offsets from LRS2-B to LRS2-R positions (but only looking at the ACAM images) determine the best value to use for the offset * Repeat the 4 steps above but Az=0 stars near the center and the end of the trajectory. === Test offsetting from LRS2-B -> R using GC1 & ACAM as a function of Az === Purpose: We want to see if the Az matters for making good reproducible offsets from LRS2-B to LRS2-R. Procedure: * Setup on a star (not saturated so probably should use V=16) using GC1 and LRS2-B * Setup on one of the GC in nearly exactly the center of the GC field (record the pixel X and Y used) * Using repeated offsets from LRS2-B to LRS2-R positions (but only looking at the ACAM images) determine the best value to use for the offset * Repeat this test for several every 40 degrees of Az.
