# twilight_zone - runs observing scripts for de Pater, de Kleer, Molter cadenced 
#                 twilight observations of planets
#
# Purpose:
#
#       Make running the Twilight Zone observing program as straightforward as
#		possible for observers and OA's without any affiliation to the project.
#		Defines easy-to-use variables that run the observing scripts requested
#		for the project.
#
# Usage:
#
#       ./twilight_zone [-timeit] [-nosetup] [-target <value>] [-nfilt <value>] [-startfilt <value>]
#
# Arguments:
#
#       target:      Name of the planet or moon you're observing (options Io, Titan, Uranus, Neptune)
#		nfilt:		 Number of filters you want to run
#		startfilt:   Which filter should you start with? If not specified do all filters
#					 Must be less than or equal to nfilt
#       timeit:      Calculate time for each filter - used for testing
#		nosetup:     Skip setup at beginning of the script. For experts only
#
# Output:
#
#		Will prompt you before running script saying how much time it takes
#       A set of images taken following the defined filters and dithers.
#		If -timeit 1, output a .log file containing start and end time
#
# Help:
#		twilight_zone -h
#
# Examples:
#
#      twilight_zone -timeit -target Uranus -nfilt 3
#
#      twilight_zone -nosetup -target Io -nfilt 9 -startfilt 7
#           * this will do filters 7, 8, and 9
#
#      twilight_zone -target Titan -nfilt 3 -startfilt 3
#           * this will do only filter 3
