QC1 parameters written into QC1 database (selection):
QC1 DB names: badpix_ft/sc | fluxavg_ft1/2/3/4 | fluxavg_sc1/2/3/4 | refpos1_ft1/sc1 | refpos2_ft1/sc1 |
coherence_avg_ft/sc | phaserms_ft/sc | coherence_ft12/sc12 | mincoher_ft12/sc12
|
|
ALGORITHM |
Description of algorithms:
badpix_ft/sc: A pixel is regarded as bad if its dark current fulfills the condition: dark_current > meandark + threshold x darkrms.
fluxavg_ft1/2/3/4 and fluxavg_sc1/2/3/4: Flux from calibration unit in e-/s. Separated for FT and SC data, and for inputs 1 to 4. The two polarimetric beams in split polarimetry are added.
refpos1_ft1/sc1 and refpos2_ft1/sc1: Position of the reference wavelength 1 (2.099 um) or 2 (2.313 um) on the detector in the 1st (lowest) spectrum, for FT and SC, respectively. Same for the 24th and 48th (only for split polarimetry) spectrum.
coherence_avg_ft/sc: Coherence for FT and SC, averaged over the six baselines.
phaserms_ft/sc: RMS of the fringe phase for FT and SC.
coherence_ft12/sc12: Wavelength-averaged coherence for FT and SC, respectively, for the six baselines, 12, 13, 14, 23, 24, and 34.
mincoher_ft12/sc12: Minimum coherence over the wavelength range for FT and SC, respectively, and for the six baselines.

|
CERTIF |
Reasons for rejection:
A good P2VM calibration should have normalized coherence above 0.85 for all baselines and wavelengths
(according to consortium). The fringe phase over wavelength should be smooth. (A jump from 0 to 360 is normal.)
