Plan for data acquisition for December 2023 run

Please make a plan for the data acquisition in December 2023 run. This is the first case to take a complete set of calibration data for all spectrograph (except for n4).

The goal of the run

    Take calibration data as much as possible to resolve the problems and improve the pipeline. Since we have all spectrographs and cameras (except for n4), try to define a standard set of data and the way to take (and reduce) in the regular operation.

The data set we take (PRELIMINARY!!) Most of them below may be replaced by just a reference to the document of the standard data set we routinely take in future.

[Higher priority]

• biases / darks (~20 / ~140 min.)
  • no telescope time needed
  • masterBiases (20 min.?) and masterDarks (140 min.?) but take n-band darks occasionally for removing persistence

• data for detectorMap (~120 min.)
  • a full set of arcs and quartz (configuration in allHome)
    • brn (5 frames per arc lamp and quartz) (60 min.?)
    • bmn (5 frames per arc lamp and quartz) (80 min.?)
  • retake a few times during the run to see the stability (is this needed?)

• data for FiberProfiles (TBD min.)
  • repeat the following sequence for [*mod4+1, mod4+2, mod4+3, mod4+4*]

• • •  (darkRoach)
      • configure to allHidden (20 min.)
      • 45 sec. quartz brn for dithers of 0.0, -0.4, 0.2, 0.0, 0.2, 0.4, 0.0 pixels (TBD min.)
      • 45 sec. quartz bmn for dithers of 0.0, -0.4, 0.2, 0.0, 0.2, 0.4, 0.0 pixels (TBD min.)
    • (mod4+x)
      • configure to mod4+x (2 min?)
      • 45 sec. quartz brn for dithers of 0.0, -0.4, 0.2, 0.0, 0.2, 0.4, 0.0 pixels (TBD min.)
      • 45 sec. quartz bmn for dithers of 0.0, -0.4, 0.2, 0.0, 0.2, 0.4, 0.0 pixels (TBD min.)
  • We may add the sequence for mod32 (or mod16) with no dithering in the above
  • take n-band dark while configuring allHidden?
  • can we replace bmn --> m?**

• data for illumination study (TBD min.)
  • take arc/quartz with/without flat screen (in allHome)
    • configure to allHome (if home keep the configuration)
    • (with flat screen)
      • remove top screen (if removed keep the screen position)
      • brn (3 frames for HgCd [TBC] and quartz) 
      • bmn (3 frames for HgCd [TBC] and quartz)
    • (without flat screen)
      • insert top screen
      • brn (3 frames for HgCd [TBC] and quartz) 
      • bmn (3 frames for HgCd [TBC] and quartz)
  • change illumination using different ring lamp position (in allHome)
    • configure to allHome (if home keep the configuration)
    • repeat the following the lamp position in [p1, p2, p3, p4]
      • Turn ring lamp p1
      • brn, 3 repeats of TBD sec. ring lamp quartz (TBD min.)
      • bmn, 3 repeats of TBD sec. ring lamp quartz (TBD min.)

[Lower priority]

• data for background study (TBD min.)
  • take sparse sky in [*allHidden, mod32, mod16*]
    • configure to allHidden (20 min.)
    • brn, 3 repeats of TBD sec. sky (TBD min)
    • bmn, 3 repeats of TBD sec. sky (TBD min.)
    • configure to mod32 (2 min?)
    • brn, 3 repeats of TBD sec. sky (TBD min)
    • bmn, 3 repeats of TBD sec. sky (TBD min.)
    • configure to mod16 (2 min?)
    • brn, 3 repeats of TBD sec. sky (TBD min)
    • bmn, 3 repeats of TBD sec. sky (TBD min.)  
  • take arc/quartz in [*allHidden, mod32, mod16?*]
    • configure to allHidden (20 min.)
    • brn, 3 repeats of arcs and quartz (36 min)
    • bmn, 3 repeats of arcs and quartz (48 min.)
    • configure to mod32 (2 min?)
    • brn, 3 repeats of arcs and quartz (36 min)
    • bmn, 3 repeats of arcs and quartz (48 min.)
    • configure to mod16 (2 min?) <-- do we need?
    • brn, 3 repeats of arcs and quartz (36 min)
    • bmn, 3 repeats of arcs and quartz (48 min.)
  • do we need take allHidden data just before each brn(or bmn) sequence like fiberProfiles data?

• data for dot penumbra study (TBD min.)
  • configure cobras at different distance from dots
  • take brn, 3 repeats of quartz
• data for uniformity (~90 min.)
  • quartz (in allHome)
    • configure to allHome

    • configure to allHome
    • brn, 3 repeats of 180 sec. twilight, InR = -90, 0, 90 (13 min. x 3)

    • configure cobras at different theta/phi angle
    • take brn, 3 repeats of quartz
  • (defocus data for Kota’s study if we have time)

Data analysis plan

• Generate CALIBs (a good chance for NAOJ to make CALIBs)
  • masterBiases/masterDarks --> constructPfsBias.py & constructPfsDark.py
  • detectorMap --> reduceArc
  • fiberProfiles --> reduceProfiles
  • flat --> TBC
• QA analysis 
  • run detectorMapQA (based on Wilfred's notebook?)
  • run extractionQA (Hamano-san will prepare a script)
