FITS tables

(File types: .FIT .fit .FITS .fits .GSC .gsc). Mixed capitalisations, such as .Fit, are also supported. To access a FITS table in the current directory you need only supply the file name. To access a FITS table in another directory you should precede the file name with an absolute or relative directory specification⁵.

Usually the table component of a FITS file occurs in the first FITS extension to the file. When reading an existing FITS file CURSA will look for a table in the first extension. In cases where the table is located in an extension other than the first you can specify the required extension by giving its number inside curly brackets after the name of the file. For example, if the table occurred in the third extension of a FITS file called perseus.FIT you would specify:

perseus.FIT{3}

The closing curly bracket is optional. When CURSA writes FITS tables the table is always written to the first extension.
