  1. 2G Instrumentation Pipelines Sandra Castro

  2. Pipeline Products 1. Product FITS header 2. QC parameters (PAF file) 3. Naming products 4. Saving products Sandra Castro 2G Instrumentation Pipelines

  3. Pipeline Products 1 All product files created by the pipeline must be in FITS format Sandra Castro 2G Instrumentation Pipelines

  4. 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

  5. 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

  6. 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

  7. EXTNAME = ‘DET1.CHIP2’ All other HIERARCH ESO PRO HIERARCH ESO QC Multi-HDU Headers Common keywords to all extensions INSTRUME PIPEFILE HIERARCH ESO PRO CATG PRO CATG Keywords for extension 1 EXTNAME = ‘DET1.CHIP1’ All other HIERARCH ESO PRO HIERARCH ESO QC Keywords for extension 2 Sandra Castro 2G Instrumentation Pipelines

  8. Multi-HDU Headers /* Plist is my primary header */ cpl_dfs_setup_product_header(Plist, proframe, set, pars, recid, pipeid, dicid); /* Remove undesired keywords */ cpl_propertylist_erase_regex(Plist, “ESO PRO”, 0); /* Xlist is my extension header */ cpl_dfs_setup_product_header(Xlist, proframe, set, pars, recid, pipeid, dicid); /* Remove undesired keywords */ const char delkeys[] = “^(ORIGIN|TELESCOPE|INSTRUME|OBJECT|RA|DEC|EPOCH| PIPEFILE|EQUINOX|RADECSYS|DATE-OBS|MJD-OBS|UTC|LST|PICOI|OBSERVER)$”; cpl_propertylist_erase_regex (Xlist, delkeys, 0); /* Add PRO.CATG to primary header */ cpl_propertylist_copy_property (Plist, Xlist, “ESO PRO CATG”); /* Save product */ cpl_image_save(NULL, name, bitpix, Plist, CPL_IO_DEFAULT); cpl_image_save(image, name, bitpix, Xlist, CPL_IO_EXTEND); Sandra Castro 2G Instrumentation Pipelines

  9. PAF Pipeline Products 2 All QC parameters must be also saved on disk on a log file. One file per FITS extension Sandra Castro 2G Instrumentation Pipelines

  10. QC parameters – PAF file PAF.HDR.START ; #start of header PAF.TYPE “pipeline product” PAF.ID “ocam_mbias” PAF.NAME “ocam_masterbias.paf” PAF.DESC “QC file” PAF.CHCK.CHECKSUM “” PAF.HDR.END ; #end of header ARCFILE “OCAM_IMG_BIAS076_0003.fits” EXTNAME “DET1.CHIP1”; #extension name DATE-OBS “2005-03-17T12:16:44:632”; #Date TPL.ID “OCAM_img_cal_bias”; # Template id MJD-OBS “53446.5”; # Obs start QC.MBIAS.MEAN 120.2234 QC.MBIAS.STDEV 15.23445 Sandra Castro 2G Instrumentation Pipelines

  11. Pipeline Products 3 All output FITS files must be named in a unique and predictable way by the recipe Sandra Castro 2G Instrumentation Pipelines

  12. Naming Products OCAM_IMG_OBS076_0001.fits OCAM_IMG_OBS076_0002.fits OCAM_IMG_OBS076_0003.fits ocam_reduce_sci ocam_JITTERED_IMAGE_1.fits ocam_JITTERED_IMAGE_2.fits ocam_JITTERED_IMAGE_3.fits ocam_COADD.fits • no matter what input files • no matter what input parameters TEXT TEXT TEXT predictable Sandra Castro 2G Instrumentation Pipelines

  13. Pipeline Products 4 All product files must be saved on the working directory Sandra Castro 2G Instrumentation Pipelines

  14. Good news! CPL function to save PAF files CPL function to save products Planned for CPL-4.0 Sandra Castro 2G Instrumentation Pipelines

  15. 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
