Collimation and Pointing following re-installation of Rigid Secondary on SX.

01:30 Restore old secondary and primary collimation models for SX Gregorian.

  • Copy current models (made on 18 October 2011 with AO Secondary) to name.20111018.dat
cp SXSMMODSCollimation.dat SXSMMODSCollimation.20111018.dat
cp SXPMMODSCollimation.dat SXPMMODSCollimation.20111018.dat

  • Copy models made in 2011August for LUCIFER to /home/telescope/TCS/Configuration/PSF/ as SXPMMODSCollimation.2011August.dat and SXSMMODSCollimation.2011August.dat and then copy these to the default MODS names to make them active.
Andrew emailed to me these models from 2011August:

  • Revert to old Pointing Model.
    • Current MODS Pointing model is SX_Gregorian.20111018.ptmod
    • Previous MODS Pointing model in /home/telescope/TCS/Configuration/PCS/ is MODSSX.20110213.ptmod
    • Edit PCSInstrument.conf to replace SX_Gregorian.20111018.ptmod with MODSSX.20110213.ptmod

02:01 There are problems establishing communication with the rigid secondary. Steve & Michael are calling Guido and various others downtown. But this does not seem like it will be resolved soon. We are considering switching to LBCs.
