MOSCA quality test instructions

(~30 minutes total time)

Taking images

  • Get beta light source from carousel, don't drop!
  • Put beta light into FASU B, position 6, align with marks on slot edge
  • Close mirror covers or turn off all lights from dome and close the door
  • Edit the setup file for FASU B by typing editsetup on marissa.
  • Start MOSCA software, filename should be the normal name for current day in order to save images to CD
  • Run qc-script, this will:
    • take a sequence of 3 darks (not saved), 2 40 second flats (saved), 3 darks (not saved) and 2 darks (saved),
    • analyses the images, if the results are OK, accept them
    • then puts 2x2 binning on and takes 3 darks (not saved), 2 10 second flats (saved), 3 darks (not saved) and 2 darks (saved).
    • analyses the images, if the results are OK, accept them
    • check this for nice pictures
  • Take out beta light from FASU B and put back to carousel
  • Edit again the setup file as above to remove "Beta Light"
  • The whole process takes rather long time, about 23 + 7 minutes.
