One problem that took a while to deal with as a part of IFO recovery was the lack of good .snap values for the OPTICALIGN slider values.  I am told that part of this is that the values in the safe.snap files are not updated very often.  In particular, they had not been updated since before some of the suspensions were mechanically realigned to center the slider values, so the computer reboots this morning put the optics in very bad places.  (We had to hand-trend each slider value and type the values in.)

As a solution, I have created a new .req file that includes all of the OPTICALIGN values from the IFO_Align screen.  The .req file (and the corresponding .snap file) lives in /opt/rtcds/userapps/release/sus/h1/burtfiles/OptAlignBurt.req .  I have also written scripts to capture new .snap files, and restore the .snap file.  The idea is that the capture script be run just before maintenence begins, and the restore script be run at the end of maintenence. 

To run the capture script, in a terminal paste the following:

/opt/rtcds/userapps/release/sus/h1/scripts/CaptureOptAlignBurt.sh

To run the restore script, in a terminal paste the following:

/opt/rtcds/userapps/release/sus/h1/scripts/RestoreOptAlignBurt.sh

As a side note, the slider values for ITMX, ITMY, ETMX and ETMY have been accepted in the SDF system (made to be monitored, accepted, then un-monitored), so computer reboots should keep us closer, even if we forget to run the above scripts.  We should do the same with the other major suspended optics.
