Observing Plan for October 2009 Commissioning

Checks before start of commissioning

  • DONE Hardware installation (Joar)
    • AGw#4
    • IRTC
  • DONE TCS Build
    • Build 33 for LDG Commissioning
    • October 6 installation on the mountain
  • DONE Telescope setup for Left Direct Gregorian
    • DONE PSF: Global offsets for M1 and M2 and Collimation model (Dave)
      • SXPMIRTCDCollimation.20090506.dat in use, most recent
      • SXSMIRTCDCollimation.20090503.dat in use, most recent
      • Models include global offsets already, may need to update at telescope
    • DONE GCS: Connection to AGW#4 (Torsten)
    • DONE PCS: Correct pointing model (Dave)
      • LEFTPOINTINGMODEL = irtcdg.20090506.ptmod
      • This is the only pointing model made for DG so far
  • DONE Communication between AGW#4 and GCS (Torsten)
    • AGw Startup and home
    • Guide and WFSC image acquisition
    • Command line request to AGw
  • DONE Check x-flips are correct
    • Check that configuration values for PCS and GCS are set correctly (Dave)
      • LEFTXYFLIP true false for IRTCDG.  This is correct for the DG focus.
      • GCS/AGw should have the same pcsmx parameter as for LFBG (confirm with Jesper, email sent 10/02)
      • It should be the same because PCS now talks in the same right-handed PCS_XY coordinate system at both foci, and the AGw's presumably both talk in left-handed coordinate systems as seen from the instrument side of the focal plane.
    • Check with MCSPUsimulator (Michele, Doug)
  • DONE Check operation of IRTC (Doug)
