Abstract
We present the data reduction pipeline for the Herschel Infrared Galactic Plane survey (Hi-GAL). Hi-GAL is a key project of the Herschel satellite, which is mapping the inner part of the Galactic plane (|l| ≤ 70° and |b| ≤ 1°), using two Photodetector Array Camera and Spectrometer (PACS) and three Spectral and Photometric Imaging Receiver (SPIRE) frequency bands, from 70 to 500 μm. Our pipeline relies only partially on the Herschel Interactive Processing Environment (hipe). It features several newly developed routines to perform data reduction, including accurate data culling, noise estimation and minimum variance map-making, the latter performed with the romagal algorithm, a deep modification of the roma code already tested on cosmological surveys. We discuss in depth the properties of the Hi-GAL science demonstration phase data.
