Chunk File

File Format: FTCL parameter file

Name:

In chunkRoot/stripSS/muMMMMMM_V the file is named tsChunk-SS-MMMMMM.par, where SS is the stripe number, MMMMMM is the starting great circle longitude (mu) of the chunk in integer arcsecs, and S is the sky version.

In runsRoot/RRRR/V/ the file is named tsChunk-RRRR-V.par, where RRRR is the run number, and V is the rerun number.

Contains a list of all segments of Frames Pipeline Runs in a resolved chunk of sky. Not used when running target selection out of the database.

stripe               'XX'               # stripe number
startMu          'XXXXXX'               # starting great circle longitude
					# of the chunk (inclusive,
					# integer arcsecs)
endMu            'XXXXXX'               # ending great circle longitude
					# of the chunk (exclusive,
					# integer arcsecs)
skyVersion           'X'                # sky version:
                                        # -1 = untiled run (skyVersion
					# = 15 will be used in the SQL
					# database instead of -1)
                                        # 0 = targeted sky
                                        # 1 = best (aka latest photo) sky 
                                        # 2, 3, 4, ... 14 = Southern Survey sky
					# 15 = used in SQL database to designate
					# skyVersion = -1 

NOTE: to make the life of a database programmer easier, the "runs"
version of the sky, which is designated as skyVersion = -1 in a tsChunk file,
is stored as skyVersion = 15 in the SQL database. These two values are
equivalent. The highest allowed skyVersion in a tsChunk file is 14.
