*****************************************************************************
*
* Synopsis: cf_set_user_gtis(fitsfile *infits, long nseconds,
* float *timeline_times,
* unsigned char *timeline_status);
*
* Description: Apply user-defined good time intervals to timeline table.
*
* Arguments: fitsfile *infits Input FITS file pointer
* long nseconds Number of points in the timeline table
* float *timeline_times Array of times
* unsigned char *timeline_status The status flag array
*
* Calls:
*
* Returns: 0 on success
*
* History: 09.10.03 1.1 bjg Initial coding
*
* 09.12.03 1.2 bjg Bug fix. When nusergti was zero or less
* this function set all the photons to
* bad. Now it doesn't change anything.
* 04.20.04 1.3 bjg Remove unused variables
* Change format to match arg type in
* sprintf.
