| | 44 | === Testing Calibration of OWFSX === |
| | 45 | |
| | 46 | Purpose: We want to see if all of the calibrations have the right signs and angles for OWFS1 and OWFS2. |
| | 47 | |
| | 48 | * setup on an 11 mag star on the IHMP probably in the north near center of track |
| | 49 | * move all 4 guide probes to the correct RA and DEC positions from gstar or shuffle. |
| | 50 | * guide with either GC1 or GC2 |
| | 51 | * get decent focus and then check and correct any GROC |
| | 52 | * Retract ACAM |
| | 53 | * Open the PFIP shutter {{{ syscmd -P -v 'OpenShutter()' }}} |
| | 54 | * null out the X, Y, Focus, Theta, Phi from DWFS8 |
| | 55 | * To make X or Y offsets you will need to: |
| | 56 | * open the loop on the guider |
| | 57 | * make your offset with the handpaddle |
| | 58 | * clear the fiducial |
| | 59 | * watch as new fiducials are set to see if it looks good |
| | 60 | * close the loop on the guider |
| | 61 | * To make the Theta and Phi offsets you will need to: |
| | 62 | * open the loop on the TTC |
| | 63 | * make your offset with the handpaddle |
| | 64 | * clear the fiducial |
| | 65 | * watch as new fiducials are set to see if it looks good |
| | 66 | * close the loop on the TTC |
| | 67 | * The X and Y prescribed corrections are between -1 and 1. |
| | 68 | * The Theta and Phi prescribed corrections are between -10 and 10. |
| | 69 | * The Focus prescribed correction is between -0.05 and 0.05 |
| | 70 | * make small offsets with the OWFS1 and OWFS2 to get the lenslet somewhat lit, enough to turn on processing. |
| | 71 | |
| | 72 | {{{ |
| | 73 | To move the wfs probes: |
| | 74 | syscmd -T -v 'WFS1_offset_probe( dx_ang=1.0, dy_ang=0.0) ' |
| | 75 | syscmd -T -v 'WFS2_offset_probe( dx_ang=0.0, dy_ang=-0.5) ' |
| | 76 | The coordinates are in units of arcseconds. |
| | 77 | }}} |
| | 78 | |
| | 79 | * make corrections based on the OWFS1 or OWFS2 metrology offsets '''with TCS hand-paddle not with probe moves''' |
| | 80 | * report what works and does not work in the RA and TO reports or e-mail to het-operations. |
