From Dominique Boutigny

I have installed some simple stack validation tools working on CFHT data in /lsst8/boutigny/valid_cfht

Here is the content of the README file :

------------------------------------------------------------------------------------------------------------------------
This directory contains a set of utilities to validate a stack release with CFHT data

At the moment, only validation plots for the astrometry are produced

Directories :
-------------
rawDownload : contain raw CFHT images (flat, dark, bias, fringe,... corrected)
reference_plots : contain reference plots corresponding to the best results obtain so far.

Files :
-------
setup.cfht : stack environment setup
valid_cfht.sh : run processCcd taks on the cfht images
valid_cfht.sh init : create the input/ouput directories, ingest raw images and run processCcd
valid_cfht.sh : without the "init" argument, runs processCcd assuming that the directory structure exists and that the raw images have been ingested.
valid_cfht.py : run some analysis on the output data produced by valid_cfht.sh
processConfig.py : configuration parameters for processCcd
run.list : list of vistits / ccd to be processed by processCcd

Requirements :
--------------
obs_cfht : tickets/DM-1593
astrometry_net_data : SDSS_DR9 reference catalog corresponding for CFHT Deep Field #3
------------------------------------------------------------------------------------------------------------------------

Basically it produces a set of plots stored in a png image that can be compared to a reference plot corresponding to the best results obtained so far with stack_v10_0

I hope that this is useful. Just be careful that I wrote these scripts with my own "fat hand full of fingers" and that it is just basic code from a non expert. If it is useful, I can certainly add more plots to validate the psf determination, photometry, etc.

Comments, suggestions and criticisms are very welcome.
