# WCS_DESC - The definition of the WCSLAB descriptor memory structure.
#
# Description
# This include file defines the memory structures and macros needed to
# access elements of a WCSLAB descriptor. The descriptor provides all
# the necessary elements for the routine wcslab to produce a labeled
# graph.
#
# History
# 9May91 - Created the descriptor. Jonathan D. Eisenhamer, STScI.
# 15May91 - Modified the descriptor to contain only pointers to arrays.
# Two routines, wcs_create and wcs_destroy are required to
# create the arrays that are pointed to in the descriptor.
# Also seperated the include file from the wcslab.h file. jde
# 12Jun91 - Rewrote some of the labelling parameters. jde
# 20Jun91 - Redesigned much of the parameters. jde
