This outline discusses the integration of data flow systems in the context of pipeline operations at Paranal and Garching. It covers key processes from Preliminary Design Review (PDR) to commissioning, including data approval, evaluation methods, and release strategies. Emphasis is placed on template-based processing, validation of data reduction algorithms, and alternate calibration methods. Important operational guidelines, quality control measures, and batch processing strategies are also outlined to ensure efficient data handling and science operations.

  1. Pipeline Integration into the Data Flow System

  2. Pipeline Integration DICB/Archive Data Flow Operations Pipeline Library + Test Data Pipeline Team INS Commissioning Team Paranal Science Operations Public Release

  3. Talk Outline • From PDR to Commissioning • Raw Data/DICB Approval • Evaluation: Commissioning / SV • Release: Pipeline releases • Pipeline @ Paranal • Pipeline @ Garching • Maintenance: Pipeline updates and evolution

  4. DFS Deliverables: Template Schedule

  5. DFS Deliverables: Template Schedule (cont’d)

  7. From PDR to Commissioning • PDR Preparation • Reuse existing documents as templates • FDR Preparation • Prototype data reduction algorithms (test and simulated data) • Pipeline is template based, • but do we need any additional off-line processing? • Data combination, interactive processing • Coding starts only after the FDR • PAE and Commissioning • Validated data reduction algorithms (test and simulated data) • Explore alternative calibration methods

  8. DICB Approval • DICB Validation • No redefinition of existing keywords (database at www.eso.org/dicb) • Keyword names should not be too long • Avoid underscores and special characters • DPR Keyword Values • Ideally, classification rules are only based on DPR keywords • Valid values are listed in the DICB 3.0 documents • Submit proposal to DICB by FDR before using new values • Multi-HDU files • Always the same structure of data for a given data type • Data extensions come first, auxiliary and optional tables afterward

  9. Association Maps

  10. OCA Rules if DPR.CATG=="CALIB" and DPR.TYPE=="LAMP,WAVE" then { DO.CLASS = "ARC_SPECTRUM"; RAW.TYPE = "WAVE"; } • CLASSIFICATION select execute(GI_WAVE_CALIBRATION) from inputFiles where RAW.TYPE=="WAVE“ group by TPL.START • ORGANIZATION action GI_WAVE_CALIBRATION { select file as MASTER_BIAS from calibFiles where PRO.CATG=="MASTER_BIAS" and inputFile.DET.WIN1.BINX==DET.WIN1.BINX; select file as GRATING_DATA from calibFiles where PRO.CATG=="GRATING_DATA" and inputFile.INS.GRAT.NAME==INS.GRAT.NAME; recipe giwavecalibration { } product mflat { PRO.CATG="MASTER_FLAT"; } } • ASSOCIATION

  11. OCA rules: Operational environments • Pipeline (ESO Observatory, Data Organiser) • On-the-fly data processing (event driven) • Template-based processing • Static calibration database (only certified products are used) • Quality Control (ESO Headquarters, ABbuilder) • Batch processing of complete data sets (all science and calibration data produced by one ESO instrument in one night) • Best available calibrations are used => data must be organized according to the Calibration Cascade • Science Archive (CalSelector) • Web-based association of calibration data (raw and reduced) to science data
