The Herschel Space Observatory, the fourth cornerstone mission in the ESA science program, was launched 14th of May 2009. With a 3.5 m telescope, it is the largest space telescope ever launched. Herschel's three instruments (HIFI, PACS, and SPIRE) perform photometry and spectroscopy in the 55 - 672 micron range and will deliver exciting science for the astronomical community during at least three years of routine observations. Here we summarize the state of the Herschel Data Processing System and give an overview about future development milestones and plans.
The development of the Herschel Data Processing System started seven years ago to support the data analysis for Instrument Level Tests. Resources were made available to implement a freely distributable Data Processing System capable of interactively and automatically reduce Herschel data at different processing levels. The system combines data retrieval, pipeline execution and scientific analysis in one single environment. The software is coded in Java and Jython to be platform independent and to avoid the need for commercial licenses.
The Herschel Interactive Processing Environment (HIPE) is the user-friendly face of Herschel Data Processing. The first PACS preview observation of M51 was processed with HIPE, using basic pipeline scripts to a fantastic image within 30 minutes of data reception. Also the first HIFI observations on DR-21 were successfully reduced to high quality spectra, followed by SPIRE observations on M66 and M74.
The Herschel Data Processing System is a joint development by the Herschel Science Ground Segment Consortium, consisting of ESA, the NASA Herschel Science Center, and the HIFI, PACS and SPIRE consortium members.
