Throughput Tables
There are three basic types of files (FITS tables) we use with the STSDAS software package
Synphot.
- component throughput tables (usually "_syn"): each such table gives the transmission curve for an individual element or "component" in the optical path of HST+SI.
- master component lookup table ("_tmc"): contains the full directory path and name of each component throughput table to be used.
- observatory configuration or "master graph" table ("_tmg"): gives the relationship of the components to one another as encountered by a light ray tracing
each of the many distinct paths from the HST Primary Mirror to the SI detector.
These three types of synphot tables are used by the software to estimate the total throughput of any given observing mode or configuration. New synphot files or updates
are also delivered to OPUS via the same basic CDBS reference file delivery process.
The tmc & tmg tables are also kept in their own directory, called "mtab". They are uniquely named using the
uniqname
schema, with rootnames endings as described above.
Access the mtab FTP directory containing the synphot master tables (tmc & tmg).
Access FTP directories of the individual component throughput tables (current SIs):
Access the FTP directories of the individual component throughput tables for the previous generation SIs:
Access the FTP directories of the OTA-related throughput tables and the
Non-HST tables.
