NAME

fkeytab -- Copy a FITS keyword value to a FITS table element.

USAGE

        fkeytab fitsfile[ext#] keyword tblfile[ext#] column row

DESCRIPTION

This task reads a header keyword from the input FITS file ('fitsfile') and writes the value into a table element in either the same or a different FITS file. Implicit datatype conversion will be attempted if the datatypes of the keyword and the column are not the same. Whether the keyword is found or not is indicated in the parameter file.

PARAMETERS

fitsfile [file name]

The name, including extension and extension number in square brackets (e.g., myfile.fits[3]) of the FITS file containing the header keyword.

keyword [string]

Name of keyword to be read. (The name is not case sensitive.)

tblfile [file name]

The name, including extension and extension number in square brackets of the FITS table extension file to be modified. If this parameter is blank, then the input file ('fitsfile') will be used.

column [string]

Name of the table column to be modified. (The name is not case sensitive.)

row [integer, min=1, max=INDEF]

Table row number to be modified

(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 modified. If the column is an array, enter all dimensions: 23,4.

(exist) [boolean]

Whether or not the requested keyword was found.

EXAMPLES

1. Copy the NSTEP keyword from the primary array header of the FITS file myfile.fits to the 10th row of the 'OFFSET' column in the FITS table in the second extension of the same file:

          
               ft> fkeytab myfile.fits[0] nstep myfile.fits[2] offset 10
