Data model: gangs.list

General description: A gangs.list file exists separately for astro_gangs and photo_gangs for each MJD. They are used by apotransfer (originally GAP) to check that it has retrieved all the files it thinks it should have.

Naming convention: gangs.list

Approximate size: variable, of order 10 kbytes.

File type: ASCII staging list (legacy)

Read by products: ???

Written by products: ???

Example header:

# filename grp gang icc datasize TAI
#

Where the columns mean:

filename: name of file (global path on the staging machine at APO)
grp: "group" the file is in (run for imaging, MJD for spectro)
gang: not entirely sure
icc: identification of CCD
datasize: size of data stored (not file size)
TAI: timestamp
