2.1. Introduction

The following cookbooks summarise important information on usage of all aspects of HIFI data acquisition and reduction for all observing modes. You will find a summary of how observations were carried out for a given mode, an overview of the Observation Context, from calibration to Level 2.5, and a description of the data reduction workflow including post-processing recipes to e.g. inspect emission in the OFF positions.

Although much care was taken to provide complete details for each mode, it is worth consulting all cookbooks in case some details were not repeated in every cookbooks.

To complement the cookbooks, you have access to some useful scripts (containing detailed comments) via HIPE that will guide you in writing your own scripts, and teach you more in-depth methods of data reduction for specific tasks e.g. artifacts cleaning, HEB correction etc... (see Figure 2.1). You can save these scripts, and adapt them to your need.
