# History:

#  v1.0 (scorder, gmoellen, jkern; 2012Apr26) == initial version

#  v1.1 (gmoellen; 2013Mar07) Lots of improvements from Eric Villard

#  v1.2 (gmoellen; 2013Apr09) Added fixsyscaltimes and calantsub methods

#                             to handle Tsys irregularities

#  v1.3 (dpetry; 2017Sept11) Added genImageName

#  v1.4 (gmoellen; 2021Jul08) fixsyscaltimes now returns True if a fix

#                             was applied, otherwise returns False

#

# This script defines several functions useful for ALMA data processing.

#

# tsysspwmap  - generate an "applycal-ready" spwmap for TDM to FDM

#                 transfer of Tsys

# fixsyscaltimes - repairs the TIME and INTERVAL columns of the MS

#                    SYSCAL subtable so that gencal properly generates

#                    the Tsys caltable

# calantsub - provides for substitution of cal solutions by antenna

#

# genImageName - generate canonical image file names

#

# To access these functions, type (at the CASA prompt):

#

# from recipes.almahelpers import *

#

# For more information about each function type

#

# help tsysspwmap

# help fixsyscaltimes

# help calantsub

# help genImageName
