# ChangeLog
# =========
#
# Version 3.58 - 2019-04-10 (JVP)
# ------------
#
# + Skip SFBLC exposure maps if SFBLC input image has EXPOSURE = 0
# 'eexpmap' task crashes otherwise
#
# Version 3.57 - 2019-03-26 (JVP)
# ------------
#
# + check_min_max_rate_col(): Remove NaN entries before min/max test
#
# Version 3.56 - 2018-08-13 (PR, JVP)
# ------------
#
# + Third call to embadpixfind included
#
# Version 3.55 - 2018-07-25 (JVP)
# ------------
#
# + Writing down the same Legal Limits ( tlmin6/7 , tlmax6/7 ) also in the FWC imaging event list: $imgFWCEvents
# Be aware that TLMIN6, TLMAX6, TLMIN7, TLMAX7 are again re-written into the final products,
# FWC and OOT imaging event files by the module 'EPICImageSize.pm'
#
# Version 3.54 - 2018-06-14 (JVP)
# ------------
#
# + Search for FWC data (evqpb) always in MOS case because peripheral CCDs are always in 'PrimeFullWindow' mode.

# Version 3.53 - 2018-06-05 (JVP)
# ------------
#
# + Search for FWC data (evqpb) only if the observing mode is 'PrimeFullWindow'. No 'PrimeFullWindowExtended' mode for MOS
#

# Several parts of the code have to be skipped if the previoues condition occurs.
# New subroutine created to check the RATE column values from a TS: 'check_min_max_rate_col'
#
# Version 3.51 - 2017-01-24 (JVP)
# ------------
#
