Cookbook/tips for creating the Phase II FLD file here.
The GIRAFFE pipeline carries out the usual steps which are described in the...
The Phase II requires you to create an FLD file from which the FLAMES fibres are allocated. This can be quite a tricky stage.
This page (will) contain a cookbook for creating this file.

This page is a summary the basics of IFS data reduction together with an introduction to some of the more advanced or complex aspects. Here we define "data-reduction" as anything that needs to be...
Reduction
The reduction of DensePak and SparsePak data is achieved using the IRAF package dohydra. This is a pretty straightforward wrapper for processing and extracting fibre data from the WIYN...
Immediately after your data reduction it is useful to explore your data before starting the analysis. Are the observations of what you intended? What are the S/N levels? What kind of things do you...
Extracting sources
Extracting sources — point or extended — will probably be necessary at some point during your analysis of your data. There are a number of ways to do this, which you use...
