8. the calibration files
This section describes the calibration files proper (located in the
calib subdirectories). The term refers
to files describing physical characteristics of specific SAX instruments.
Files describing the format of the data associated to the SAX instruments
are described elsewhere, although they may be stored
in the same directory.
The underlying idea about calibration files is that all files which comprise
only one or a few numeric values are kept in ASCII files (usually with a name
like something.coeff) while bulkier data (like relative gain images)
are kept with XAS naming conventions in XAS format data files (these will be by definition system dependent,
since XAS files use native binary format).
Some information follows about SAX calibration files.
- spacecraft
no officially supported file besides the
instrument support files; the ITESRE barycentrization
program keeps an earth.dat file here
- MECS used by mecslib routines
calibration files are described in detail in the
MECS Guided Tour and can be
accessed here
- LECS used by lecslib routine
calibration files are not officially supported
- HP-GSPC used by hpgslib routine
calibration files supplied by IFCAI are
not supported by the author
of this document
- PDS used by pdslib routines
calibration files supplied by ITESRE are
not supported by the author
