= 20160928 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) execute the specialtwilight script == On-sky engineering: == === Calibration of CWFS === Purpose: We want to calibrate the CWFS using DWFS8 on a geostationary satellite and OWFS using DWFS8 on a star for a full trajectory. '''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 * save 15 images with DWFS8 ( use 3-4 sec exposures) '''NOTE: This can be done one jove terminal as {{{startsaving}}} followed by {{{stopsaving}}}''' * offset to CWFS (-5.5 in X) * null out the offsets in X and Y only. * 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 15 images with CWFS (use 3-5 sec exposures) * move back to DWFS8 (+5.5 in X) * repeat the above steps 2 more times '''Now we start on 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 * 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 * 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 WFS8 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: going back to the geostationary satellite and then choosing a new star at the next Az in the list: 180, 234, 292, 335, 0. '''NOTE: If the geostationary satellite goes into eclipse then just skip those steps.''' === doing globular clusters with VIRUS === Purpose: We need to fill the IFU with lots of stars. Take a bright GC and move it to one position in the IFU array: between slot 94 and 95. Procedure: * Select a bright globular cluster a little before center of track (try to avoid the CCAS tower). * Using do_shuffle put the center of the GC between IFU 95 and IFU 95. This should be an offset of +50 in Y from IFU 095. Double check with setup images. If you can not get this to work then you can use gstar2. * 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 360 second exposure at each dither. * 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.
