Calibration Results & Products: TV1

  1. Detector Properties
    1. SBC
      1. Flats:
        Raw and "P-flats" for all filters, features, wavelength response, repeatability, defect level.
      2. Darks:
        Dark rate, vs. time, vs. TSBC, vs. MCP current, dark structure, model, hot pixels.
      3. Throughput:
        Calibration, monitor vs. time, throughput vs. filter.
    2. HRC [Build 1]:
      1. Min stable TCCD vs. interface plate T
      2. Darks:
        Dark structure, Hot pixels vs. TCCD, Dark rate vs. TCCD
      3. Bias frames
        Bias level vs. gain, stability, readnoise vs. gain, Superbias and its application (?)
      4. Gain measurements
      5. Charge Transfer Efficiency
        CTE vs. exposure level, TCCD, uncertainty
    3. WFC [Build 1]:
      1. Min stable TCCD vs. interface plate T
      2. Noise problems
  2. Internal calibration system verification:
    WFC, HRC, and SBC count rates vs. filter, comparison with model, D2 lamp degradation, improvements to D2 lamp filter.
    1. Tungsten lamps (HRC, WFC)
    2. Deuterium lamp (SBC)
  3. Geometry (WFC, HRC, SBC)
    FOV location, plate scale, distortion
  4. Dispersers (prisms and grism)
    Relative pixel vs. wavelength, comparison to model, Flux vs. order distribution.
    1. UV Prisms (SBC, HRC)
    2. Grism (HRC, WFC)
  5. Filter throughput (component level results)
