INTEGRAL data

INTEGRAL is an integral-field spectroscopic facility deployed at the Nasmyth focus of the WHT, and channels the light into WYFFOS fibre spectrograph. Up to six fibre bundles are available, although only three bundles are used in normal operation, with field sizes ranging from 10 to 40 arcseconds and different fibre core sizes. These options allow observers to make the most efficient use of the prevailing seeing conditions.

Data-reduction facilities for the instrument are provided by the INTEGRAL IRAFpackage which contains some standard tasks from other IRAF packages (such as ONEDSPEC, SPECRED, and CCDRED) and some custom tasks designed to deal with INTEGRAL data. The package can be downloaded from the IAC web pages along with the package user manual, which contains installation instructions and a description of the available reduction software. It should be noted that to compile the INTEGRAL package requires the Starlink public-domain algorithms (PDA) package to be present on your machine (see SUN/194).
