QC1PARAM QC1 parameters written in QC1 database:
QC1 DB names: sensit | conver | backgd_mean | backgd_sigma | fwhmx | fwhmy
All parameters are calculated by the pipeline recipe.
ALGORITHM Description of algorithms:
sensit: sensitivity, the estimated limiting flux expected in an 1 hour on-source integration of a point source detected with S/N of 10.
Units: mJy at 10 sigma in 1 hour
conver: conversion factor between ADU and Jy.
F(total observed) / F(model) in ADU/Jy, where F(total observed) is the measuered and F(model) is the predicted flux
backgd_mean: background level determined from the half-cycle frames
backgd_sigma: noise of the background level
fwhmx: FWHM (in pixels) of the fitted profile in X direction
fwhmy: FWHM (in pixels) of the fitted profile in Y direction
CERTIF Reasons for rejection:
extremely weak or invisible star
