; NAME:
;       HW_CAL__DEFINE
;
; PURPOSE:
;       HW_CAL__DEFINE defines the class HW_CAL. Objects of this
;       class contains calibration data and routines 
;       for the EIS instrument on SOLAR-B.
;
; CATEGORY:
;       Hansteen/Wikstol Data analysis SW
;
; CALLING SEQUENCE:
;       The HW_CAL__DEFINE procedure is not called directly. An
;       object of class HW_CAL is created with the following
;       statement:
;                 cal = obj_new('hw_cal')
; INPUTS:
;
; KEYWORD PARAMETERS:
;
; OUTPUTS:
;       Objects of type HW_CAL. The object has the following
;       instances:
;                caldir: calibration data directory 
;                        (e.g. /ssw/solarb/eis/data/cal/)
;                dc_file: File name of dark current data
;                ff_file: File name of flat field
;                aeff_file: Name of file containing effective area data
