In this section, a simple run-through of the extraction process using Starlink software is given. The cookies section gives answers to specific questions and solutions to common problems.
Before you start the extraction you will have to do the detector-specific preparation of your data (most likely to remove CCD-related effects). If you have not done this, refer to Image Preparation for an outline of the procedure, and Other Sources of Information for pointers to documentation of the process.
