The routine SXT_FLUX reads the thermal response function data from
a file. Although it is not normally necessary, the response function file can be read directly
using the following commands:
IDL> restgen, file=file, str=response
** Structure MS_125794338005, 5 tags, length=5280: TEMP FLOAT Array(51) ELECTS FLOAT Array(12, 51) PHOTONS FLOAT Array(12, 51) ELEM STRING Array(15) ABUN FLOAT Array(15)Note, that the response file may be updated from time to time. The name contains the date of the last update. In this data structure, the variable TEMP is Log10(), ELECTS are the number of CCD electrons (not DN) per sec for EM cm, and PHOTONS is the corresponding number of photons. The first dimension of these two dimensional arrays is arranged so that columns 0 to 5 correspond to the filters in increasing thickness from 0=open to 5=Be119 and assuming the pre-launch entrance filter transmission. NOTE: This is not the normal SXT filter numbering scheme. Columns 6 to 11 correspond to the same filters but with no entrance filter. By combining the corresponding columns in the appropriate ratio, it is possible to quickly compute the SXT response for any size hole in the entrance filter.
