# Astro::FITS::Header::AST(3pm)

Manipulates FITS headers from an AST object

## NAME

Astro::FITS::Header::AST - Manipulates FITS headers from an AST object

## SYNOPSIS

```
  use Astro::FITS::Header::AST;
  $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo );
  $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo,
                                          Encoding => 'FITS-IRAF' );
  $header = new Astro::FITS::Header::AST( Cards => \@cards );
```

## DESCRIPTION

This module makes use of the Starlink::AST module to read the FITS HDU from an AST FrameSet object.

It stores information about a FITS header block in an object. Takes an hash as an argument, with an array reference pointing to an Starlink::AST FramSet object.

## REVISION

`$Id`$

## METHODS

- **configure**

  Reads a FITS header from a Starlink::AST FrameSet object

  ```
    $header->configure( FrameSet => $wcsinfo );
  ```

  Base class initialisation also works:

  ```
    $header->configure( Cards => \@cards );
  ```

  Accepts a reference to an Starlink::AST FrameSet object.

  If a specific encoding is required, this can be specified using the Encoding argument. Default is FITS-WCS if no Encoding is given. Note that not all framesets can be encoded using FITS-WCS.

  ```
    $header->configure( FrameSet => $wcsinfo, Encoding => "Native" );
  ```

  If Encoding is specified but undefined, the default will be decided by AST.
