Pipeline Products 1. Product FITS header 2. QC parameters (PAF file) 3. Naming products 4. Saving products Sandra Castro 2G Instrumentation Pipelines
Pipeline Products 1 All product files created by the pipeline must be in FITS format Sandra Castro 2G Instrumentation Pipelines
DRS keys QCs setup header product header Product FITS header creating a product header empty or raw header cpl_dfs_setup_product_header() Sandra Castro 2G Instrumentation Pipelines
Setup Header cpl_error_code cpl_dfs_setup_product_header( cpl_propertylist * header, const cpl_frame * proframe, const cpl_frameset * set, const cpl_parameterlist * pars, const char * recid const char * pipeid const char * dicid ) recid ocam_mbias pipeid PACKAGE/PACKAGE_VERSION dicid PRO-1.15 Sandra Castro 2G Instrumentation Pipelines
Setup Header • Copy to header: ORIGIN, TELESCOPE, INSTRUME, OBJECT, RA, DEC, EPOCH, EQUINOX, RADECSYS, DATE-OBS, MJD-OBS, UTC, LST, PI-COI, OBSERVER. • Copy all the HIERARCH.ESO._ keywords, with the exception of the HIERARCH.ESO.DPR._, and of the .PRO._ and .DRS._ keywords. • If found, remove the HIERARCH.ESO.DPR._ keywords from header. • If found, remove the ARCFILE and ORIGFILE keywords from header. • Add to header the PRO keywords: PIPEFILE, PRO.DID, PRO.REC1.ID, PRO.REC1.DRS.ID, PRO.REC1.PIPE.ID, PRO.DATANCOM, PRO.CATG, and PRO.TYPE. http://archive.eso.org/Tools/DidRep/DidRepWebQuery ESO-VLT-DIC.PRO Sandra Castro 2G Instrumentation Pipelines

Pipeline Products 4 All product files must be saved on the working directory Sandra Castro 2G Instrumentation Pipelines
Good news! CPL function to save PAF files CPL function to save products Planned for CPL-4.0 Sandra Castro 2G Instrumentation Pipelines
Pipeline Products 1. Products must be FITS files 2. QCs are written on headers and PAF files 3. Names must be unique and predictable 4. Products are saved on the working directory Sandra Castro 2G Instrumentation Pipelines
