SUBROUTINE WCI1_INIT( STATUS ) *+ * Name: * WCI1_INIT * Purpose: * Load ADI definitions required for WCI operation * Language: * Starlink Fortran 77 * Invocation: * CALL WCI1_INIT( STATUS ) * Description: * Loads those class definitions required by the WCI subroutine group. * Results in the following classes being defined, * * Pixellation - Describes pixel grid w.r.t. some fiducial point * Projection - Describes a map projection * CoordSystem - Describes an astronomical coordinate system * * Methods are defined to read and write WCS information from HDS and * FITS files. * Arguments: * STATUS = INTEGER (given and returned) * The global status. * Examples: * {routine_example_text} * {routine_example_description} * Pitfalls: * {pitfall_description}... * Notes: * {routine_notes}... * Prior Requirements: * {routine_prior_requirements}... * Side Effects: * {routine_side_effects}... * Algorithm: * {algorithm_description}... * Accuracy: * {routine_accuracy} * Timing: * {routine_timing} * External Routines Used: * ADI: * ADI_REQPKG - Load a package from the load path * Implementation Deficiencies: * {routine_deficiencies}... * References: * WCI Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/wci.html * Keywords: * package:wci, usage:private * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
