IRAM NOEMA
Data Reduction CookBook
September 2010
Version 5.0

This document describes how to reduce NOEMA observations and gives some ideas to perform first analysis and imaging. Sect. explains how to get started, from planning your trip to Grenoble to having a project account. The standard procedure to calibrate NOEMA data with the CLIC software package is described in Sect. . A few instructions to start the data analysis with the MAPPING software package are given in Sect. . A theoretical description of the calibration as well as a description of the extended pipeline (or AoD) `First Look` report are annexed in Apps. and respectively.
