NAME

Astro::FITS::HdrTrans::ESO - Base class for translation of ESO instruments

SYNOPSIS

use Astro::FITS::HdrTrans::ESO;

DESCRIPTION

This class provides a generic set of translations that are common to instrumentation from the European Southern Observatory. It should not be used directly for translation of instrument FITS headers.

COMPLEX CONVERSIONS

These methods are more complicated than a simple mapping. We have to provide both from- and to-FITS conversions All these routines are methods and the to_ routines all take a reference to a hash and return the translated value (a many-to-one mapping) The from_ methods take a reference to a generic hash and return a translated hash (sometimes these are many-to-many)

to_ROTATION

Derives the rotation angle from the rotation matrix.
