NAME

ftabpar -- Copy the value of a FITS table element to the parameter file.

USAGE

        ftabpar fitsfile[ext#] column row 

DESCRIPTION

This task reads the value of an element in a FITS table extension (either an ASCII or a binary table) and writes it as a string to the 'value' parameter in the parameter file. If the element is undefined then the task parameter 'undef' will be set to "yes".

PARAMETERS

The name, including extension and extension number in square brackets (e.g., myfile.fits[3] ) of the input FITS file to be read. By default the first extension will be read.

column [string]

Name of the table column to be read.

row [integer]

Row number to read.

(element = 1) [string]

If the column contains an array of values (i.e., a vector column in a binary table) then this is the number of the element within the vector to be read. If the column is an array, enter all dimensions in the form 10,3.

(value) [string]

Returned value read from the table.

(undef) [boolean]

Is the value read from the table undefined?
