/*******************************************************************************
* Johns Hopkins University
* Center For Astrophysical Sciences
* FUSE
*******************************************************************************
*
* Usage: cf_pack combined_exposure_list out_file_name.fit
*
* Description: Write the 8 segments (1alif, 1blif etc...) into a single fits
* file with 8 extensions (in addition to the primary array).
*
* History: 04/08/05 tc v1.0 First release
* 05/02/05 wvd v1.1 Copy SPEC and WOFF keywords to
* output file.
* 06/03/05 wvd v1.2 Delete unused variables.
* 06/29/05 wvd v1.3 Set keyword COMB_COR = COMPLETE.
* 09/30/05 wvd v1.4 Update archive search keywords.
* 03/23/06 wvd v1.5 If a segment is missing, write
* an empty image extension.
* 05/19/06 wvd v1.6 Write an index to the file
* extensions to the primary HDU.
* 05/24/06 wvd v1.7 Remove SPEC* keywords from
* primary HDU.
* 05/29/06 wvd v1.8 Use while construction to
* delete WOFF* keywords.
* 06/22/06 wvd v1.9 Truncate APER_ACT from (for
* example) MDRS_LIF to MDRS.
* 08/14/06 wvd v1.10 Tinker with code to copy SPEC
* keywords to new file header.
* 04/07/07 wvd v1.11 Clean up compiler warnings.
* 08/27/07 bot v1.12 Changed TINT to TLONG l.163,214,
* and 215 ; added L to every number
* occurence related to i and j ;
* Changed i to k l.123 to 131 to
* keep an int in this case
