*************************************************************************
*
* synopsis: cf_write_extracted_spectrum(infile, aperture, nout, wave_out,
* flux_out, var_out, counts_out, weights_out, bkgd_out,
* bpix_out, outrootname)
*
* Description: Write the results of the data reduction to a file.
* Information from the header is used to generate the name
* of the output file. Aperture coding is as follows:
*
* 1-8 -> LiF[HIRS,MDRS,LWRS,PINH], SiC[HIRS,MDRS,LWRS,PINH]
*
* Arguments: fitsfile infile : pointer to Intermediate Data File
* int aperture : Target aperture (values are 1 to 8)
* int valid_spectrum: True if spectrum contains photons.
* long nout : number of tabulated points
* float wave_out : Output wavelength array
* float flux_out : Output flux array
* float var_out : Output variance array
* long counts_out : Output counts array (in counts)
* float weights_out : Output weights array (in counts)
* float bkgd_out : Output background array (in counts)
* short bpix_out : Output bad pixel spectrum
* char outrootname: Optional output file name
*
* Returns: 0 if successful
*
* HISTORY: 02/10/03 1.1 RDR started work
* 02/28/03 1.2 peb Added header files to file and tidied
* code using lint.
* 03/12/03 1.3 wvd Output ERROR = sqrt(var_out)
* 03/31/03 1.4 wvd Update keywords FILENAME, FILETYPE,
* and APER_ACT.
* 05/22/03 1.5 wvd Direct cf_error_init to stderr.
* 05/29/03 1.6 rdr Added bad pixel column
* 06/03/03 1.7 rdr Change naming convention to allow
* hist data
* 07/17/03 1.9 wvd Test var_out before taking sqrt.
* Change calfusettag.h to calfuse.h
* 10/01/03 1.10 wvd Modify verbose levels.
* 11/10/03 1.11 wvd Correct numbering scheme for HIRS
* and MDRS apertures.
* 02/13/04 1.12 wvd Correct error in COMMENT lines.
* 03/03/04 1.13 rdr Populate archive search keywords
* 03/05/04 1.14 wvd Change name of POTHOLE column
* to QUALITY.
* 03/24/04 1.15 wvd If valid_spectrum=FALSE, write
* warning message to file header.
* 04/06/04 1.16 bjg Include string.h and ctype.h
* 04/09/04 1.17 wvd If valid_spectrum=FALSE, set
* EXPTIME = 0 in file header.
* 04/27/04 1.18 wvd Move conversion from variance
* to sigma from this routine to
* cf_optimal_extraction.
* 06/11/04 1.19 peb Added the -r option to override the
* default rootname
* 02/01/05 1.20 wvd Revert to standard FITS binary
* table format for output file.
* 04/11/05 1.21 wvd In HIST mode, don't write SIA
* table to output spectral file.
* 06/03/05 1.22 wvd Return status from cf_copy_hist_header.
* 06/03/05 1.23 wvd Change cf_copy_hist_header to type void.
* 08/11/05 1.24 wvd Delete FITS_write_date from
* cf_copy_hist_header.
