Data Processing Workshop NHSC, Pasadena, CA 02 – 04 February 2011 Stephan Ott VG #4 PACS Overview of Herschel Data Processing The system combines for the first time data retrieval, pipeline execution and scientific analysis in one single environment All tools for data reduction and analysis, e.g. also the expert applications for e.g. instrument calibration are part of the Data Processing System. Therefore the community has access to the same system as the instrument experts The Herschel Data Processing software is coded in Java/Jython to be license free and portable for different operating systems Formal support is provided for Windows XP, Vista and Windows 7,Linux, Mac OS X 10.5 ("Leopard") and Mac OS X 10.6 ("Snow Leopard") Herschel Science Centre (ESA), the Instrument Control Centres (HIFI, PACS and SPIRE) and NHSC jointly manage and contribute to the Herschel Data Processing System

Data Processing Workshop NHSC, Pasadena, CA 02 – 04 February 2011 Stephan Ott VG #5 PACS Overview of Herschel Data Processing Herschel Data Processing is a major project, with over 200 contributors and currently 60 full-time equivalents working on calibration, coding, documentation, quality control, testing and tutoring Very distributed development – we work 24/5 (and often 24/7) on Herschel Data Processing System 300 data processing related software tickets are raised – and resolved – each month A major HIPE version is released around each three months. This is currently HIPE 5.0 Minor HIPE versions (currently 5.2) are released around each three weeks. These serve also as the operational version to generate the standard products All releases can be downloaded via Latest HIPE developer releases are available via

Data Processing Workshop NHSC, Pasadena, CA 02 – 04 February 2011 Stephan Ott VG #13 PACS Herschel Pipeline Processing and Data Quality Control Pipelines are executed on the ESAC Grid to produce Herschel Products to different reduction levels –Level 0raw data –Level 1instrumental and satellite effects removed –Level 2scientific analysis can be performed The data are available in the Herschel Science Archive after the processing is finished (usually on the same day of reception of the data from the satellite) The fast data quality control cycle by the Technical Assistants and Instrument Calibration Scientists takes a few days –data quality control is a combination of automatic screening and manual inspection –quality control reports are electronically distributed to experts

Data Processing Workshop NHSC, Pasadena, CA 02 – 04 February 2011 Stephan Ott VG #14 PACS Bulk and on-demand reprocessing Currently HSC performs a bulk reprocessing of all data taken up to now twice a year using an even HCSS version (HCSS 2, 4, 6, 8, …) Bulk reprocessing with HCSS 4 is nearly complete Automatic quality control is performed using the latest quality control flags Spot-checks are performed on a few observations Users can request reprocessing of observations with the latest operational release using on-demand processing
