Starting Config: PEPSI PFU

Night Log:

UT 02:06 - closed for thick clouds overhead, humidity only 68%. LBCs powered up, taking test biases

-blue bias noisy, otherwise ok

UT 02:07 - waknig up MODS-2, taking test snaps

-snaps look ok

UT 03:43 - still closed - allsky looks awful but humidity remains (relatively .. hehe) low (60%)

UT 04:14 - might be improving? can see the MW, but this could also be a sucker-hole

UT 04:55 - taking 25 biases for each LBC -the slight improvement in cloud thickness quickly reversed as predicted by S. Allanson

UT 07:21 - had to run red fits flush for M2R 0046-0048

UT 09:50 - 5" dual grating flasts got 'propid calibration timed out' error - aborted and retried -went through

UT 10:40 - had a suckerhole few minutes ago....then the dark evil rolled in < 60 seconds...impressive!

UT 11:08 - powering off the LBCs

UT 12:09 - humidity risiing, particle counts up, and in 12deg twilight, we are done

UT 12:10 - putting MODS-2 to sleep. - All grating and imaging modes done for MODS-2 along with biases

DONE!

Proposed Plan of Action:

  • PEPSI
    • PFU Checkout
      • collimation
      • PFU alignment check for M3
    • PEPSI Pointing Mode - 2hr Medium/High - any conditions
      • Remove retro-reflecting dichroic (to give full FOV)
      • Take images with PFU (Active mode)
      • Need ~28 stars (10th mag or so)
        • PtStars (IRAF) will generate stars based on LST
        • minimized long azimuth slews
      • Analysis with TPOINT - D. Thompson
      • Can do in poor seeing/clouds
  • AGW-2
    • verify cover is flipped and not vignetting - HIGH
    • Field Aberration - field_collect - collect both in parallel
      • Fields:
      • BS9177 18:39:33.7 +49:05:38.0
      • StoneP1 22:37:45.0 -01:13:40.45
      • BS9188 23:30:33.4 +38:18:57.0
      • BS9107 03:32:03.0 +37:20:40.0
  • LBC
    • Standard photometric fields (new ones ready) - requires clear skies (any seeing) - required for ZP calibrations
    • Spectro-photometric standards - requires clear skies (any seeing) - required for ZP calibrations
    • Twilight Flats all filters - High (4 x 0.5 hrs - likely min two nights to complete)
    • LBC Pointing Model - (3hr) - any conditions
      • Standard Method
        • PtStarrs - please choose targets > 80 deg elevation (more than 1 or 2)
        • Run TMS passively - run 1 reference at the beginning
        • Need stable temperatures
        • Turn on PCS logging
        • Need to collimate at each star
        • Chip 2 only exposure
  • MODS-2
    • MODS Rotator Center measure (use M71 at beg of night or M52 later)
      • requires pointing mask (40" square field stop & dot-circle with radius 45") - high (0.5hr)
    • MODS AGW 5- Measure Rotator zero point (mask alignment) - high (0.5 hr) - mask exchange required

      • Prism
    • Test Science OB
      • imaging

      • Imaging check
        • dither in field (0.5hr) -
        • dither out of field (0.5hr) - M52 K and some J-band
