| | 5 | === CWFS+WFS Loop Control Tests === |
| | 6 | |
| | 7 | * Make sure your stack is pretty good (RSE < 250) |
| | 8 | * Make sure GROC is pretty well set |
| | 9 | * Select a 11th mag target near the start of the track for all probes and targetted on IHMP using shuffle and shuffle_config_matt4 |
| | 10 | * Setup on IHMP |
| | 11 | * Center up both guide probes and start guiding on one of the guiders |
| | 12 | * Set Exposure times for CWFS, WFS1 and WFS2 to about 5 seconds to assist in centering. |
| | 13 | * Offset to CWFS using {{{syscmd -T 'offset_trajectory(dx_ang=-5.5, dy_ang=0.0, adjust_probes="true")'}}} |
| | 14 | * Tweak up the position on the IHMP using further offset_trajectory commands. |
| | 15 | * Center up both WFS using mgp -grid or mgp -poff. See {{{mgp --help}}}. This requires "Process Images" to be checked. |
| | 16 | * Null out focus on WFS1. NOTE: WFS1 seems to perform better than WFS2 at the edges of the track |
| | 17 | * Start metrology loop and Activate the loop on WFS1. |
| | 18 | * '''As per normal please have the loops active for WFS2, CWFS even through they are not closed''' |
| | 19 | * Increase the exposure time for the CWFS, WFS1 and WFS2 to greater than 20 seconds for data taking but do not saturate. |
| | 20 | * Hit "store images" and "Start Metrology Loop" for GC1, GC2, WFS1, WFS2, TT, CWFS, DMI (although there are no images for DMI) |
| | 21 | * Monitor the WFS1 and WFS2 to make sure the X and Y positions do not exceed 1.5". If they do then make a correction. |
| | 22 | * Run until the end of the track. |
| | 23 | |
| | 24 | Repeat test: choosing a new star at the next Az in the list: 180, 234, 292. |
| | 25 | - For each test, please note the star and end time. |
| | 26 | |
| | 27 | === Magnitude limits for CWFS, OWFS1 and OWFS2 === |
| | 28 | |
| | 29 | Purpose: This is to come up with the minimum star magnitudes and optimal exposure time ranges for each wfs. |
| | 30 | |
| | 31 | * Must be clear for this test |
| | 32 | * Select a star of known magnitudes (preferably from the SDSS catalog or at least in a SDSS field |
| | 33 | * run do_shuffle on the field and see what magnitudes have been selected for the WFS1 and WFS2. |
| | 34 | * record the RA and DEC for the OWFS probes. |
| | 35 | * look at the shout.probestars and report those stars and magnitudes (I think there should be 5 magnitudes for viable SDSS fields). |
| | 36 | * setup on the field on the CWFS and WFS as done in the previous tests. |
| | 37 | * near the center of the track please save images with CWFS and WFS with exposures of at least 15 seconds but not saturated. |
| | 38 | |
| | 39 | Repeat this test with several stars with different SDSS CWFS target magnitudes (11th, 12th etc) |
| | 40 | |
| | 41 | === Characterize LRS2-B to LRS2-R offsets === |
| | 42 | |
| | 43 | * Start a trajectory |
| | 44 | * setup on ACAM and one guide probe at the LRS2-B location. |
| | 45 | * offset from LRS2-B to LRS2-R using: {{{B2R: syscmd -T 'offset_trajectory(dx_ang=-103, dy_ang=+3, adjust_probes="true")'}}} |
| | 46 | * Guider should stay in Active mode |
| | 47 | * Allow guider to catch the star and drag to the final position |
| | 48 | * once the guider has settled to position measure the position on ACAM and report in the RA report. |
| | 49 | * have the TO center the object on the LRS2-R and set new guider fiducial. |
| | 50 | * offset from LRS2-R to LRS2-B using: {{{R2B: syscmd -T 'offset_trajectory(dx_ang=103, dy_ang=-3, adjust_probes="true")'}}} |
| | 51 | * Guider should stay in Active mode |
| | 52 | * Allow guider to catch the star and drag to the final position |
| | 53 | * once the guider has settled to position measure the position on ACAM and report in the RA report. |
| | 54 | |
| | 55 | Repeat this test 5 times. |
| | 56 | |
| | 57 | == Closed dome or cloudy tests == |
| | 58 | |
| | 59 | === Full set of Cals to test CAMRA === |
| | 60 | |
| | 61 | Purpose: We have a new CAMRA software and need to run it through its paces. IT requires full sets of cals including sky flats. |
| | 62 | |
| | 63 | * Take LRS2 sky flats as per normal but only a single VIRUS sky flat is required not the special cals. |
| | 64 | * Take a full set of cals for LRS2 and VIRUS |
| | 65 | * Take 3 six minute darks for both LRS2 and VIRUS |
| | 66 | |
