Detailed Description

SDFITSTable is a FITSTable which follows the Single Dish FITS Convention.

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

FITSTable

Etymology

SDFITSTable is derived from FITSTable. It contains additional checks and behaviour appropriate to the Single Dish FITS Convention hence this is a Single Dish FITS Table, or SDFITSTable.

Synopsis

This class behaves much like FITSTable. It additionally verifies that the indicated HDU in the input FITS file follows the SDFITS convention (it has all of the required columns) and it treats keywords as virtual columns when appropriate. These virtual columns will appear as fields in the currentRecord and description and will NOT appear in the keywords.

Example

Motivation

It was useful to encapsulate this behaviour in a class so that the checks on a valid SDFITS table and the treatment of keywords as virtual columns would not need to appear everywhere it might be used.
