Information On DQC Plots And Log
This document describes the QC and log information available on the Vista Progress report page.
SUMMARY FILE INFORMATIOn
Columns:- note the 18 entries, one for each detector or tile in running order 1-18 for each catalogue file summarised
- Run no. - filename using CASU naming convention
- Ext - extension number or "tl" if from tile catalogue
- Object Name - value from OBJECT keyword
- RA - recorded telescope Right Ascension
- Dec - recorded telescope Declination
- Equinox - value of EQUINOX keyword
- AM - average of start and finish airmass
- Date UT - as it says
- Exp - value of EXP_TIME (s) from header, this is equivalent to DIT
- Filt - filter name
- Seeing - average of FWHM (arcsec) for stellar sources on detector
- Sky - estimate of sky background per pixel (ADU)
- Noise - estimate of sky rms noise per pixel (ADU)
- Ellipt - average ellipticity of stellar sources on detector
- APcor - aperture correction for default "core" size (default 3 pixels radius, 2.0 arcsec diameter)
- STDrms - rms error (arcsec) in astrometric solution
- MagLim - estimate of 5-sigma limiting magnitude for stellar sources
- Totexp - product of DIT*NDIT*NJITTER (x2 if standard tile) i.e. total exposure time for majority of pixels
13. value of the JITTER_X keyword (Offset in x [arcsec])
14. value of the JITTER_Y keyword (Offset in y [arcsec])
