JCMT Pointing Reports - 2006

JCMT Pointing Reports - 2006

  • Jan 29 - CW inclinometry OK - and Fourier analysis of ripple
  • Feb 03 - Fourier analysis of ripple : no need for alarm
  • Feb 13 - Pointing & Focus checks for January & February 2006
  • Feb 13 - JCMT shuts down for engineering work preparing the antenna for the arrival of SCUBA-2 in ~September. Pointing will resume in ~July once the antenna is returned to the Operations crew.
  • Jul 21 - THI.tide corrected to reflect 33 leap seconds (since 1972). This will require compensation within the model.
  • Aug 21 - CW inclinometry - first full CW run since SCUBA-2 engineering shutdown
  • Aug 22 - CW inclinometry fails, but reveals evolution in TY (Ch2)
  • Aug 23 - CW inclinometry OK
  • Aug 24 - RxA pointing and CCW inclinometry - both rather unsatisfactory
  • Aug 25 - CW and CCW inclinometry - both yield low-amplitude TY data
  • Aug 26 - CW and CCW inclinometry again - low-amplitude TY data again
  • Aug 29 - CW and CCW inclinometry with elevation drives disabled: TY amplitude normal
  • Aug 30 - CW inclinometry with updated software : TY amplitude truly normal
  • Aug 31 - RxA pointing
  • Sep 01 - Inclinometry sanity check
  • Sep 01 - RxA pointing: mo' . . . and bettah !
  • Sep 05 - Pointing quality since model installation
  • Sep 14 - Pointing quality update
  • Sep 16 - Inclinometry OK
  • Sep 25 - Pointing quality update
  • Oct 03 - Inclinometry OK
  • Oct 10 - Inclinometry OK
  • Oct 15 - Inclinometry interrupted by earthquake
  • Oct 18 - Inclinometry following earthquake
  • Oct 23 - Pointing quality update
  • Oct 27 - CW Inclinometry and pointing following central bearing adjustment
  • Oct 28 - Pointing model update
  • Nov 01 - CW/CCW Inclinometry OK
  • Nov 04 - CW/CCW Inclinometry OK
  • Nov 07 - Pointing model update
  • Nov 14 - CW inclinometry too noisy to use
  • Nov 18 - HARP pointing
  • Nov 27 - Recent pointing problems w/RxA
  • Dec 13 - Allsky pointing with RxA - azimuth performance still awful.
  • Dec 18 - (RxA) pointing update
  • Dec 18 - HARP pointing
  • Dec 29 - (RxA) pointing update
