---+ Update the JSDC in 2020 (v2020 ?) This page gathers notes on the overall process to obtain the updated JSDC catalog (v2020) based on Simbad SPTYPE + VJHK mags (tycho2+2MASS). ---++ SearchCal changes The JSDC_BRIGHT scenario retrieves GAIA DR2 information ---+++ Meta-data of New columns: ---++ JMDC inputs See the full procedure at /SCALIB/DEVELOPMENT/alx/config/JMDC/scriptHandleLastVersionOf_JMDC_dot_xls_ToProduceJMDC_dot_fits.sh This script has the following dependencies: stilts + gdl (astro lib ie MRDFITS + gdl mpfit procedures). export GDL_PATH="/home/bourgesl/apps/astron/pro/:/home/bourgesl/dev/gdl/src/pro/:/home/bourgesl/dev/gdl/src/pro/CMprocedures/" Inputs: * JMDC: get latest JMDC catalog from http://jmdc.jmmc.fr/ by clicking on the CSV button (top) * JSDC (input catalog) to compute LDD/UD using gdl script (all SearchCal columns needed) Command: ./scriptHandleLastVersionOf_JMDC_dot_xls_ToProduceJMDC_dot_fits.sh JMDC_full_20200730.csv gdl -e "make_jsdc_script_simple,\"JMDC_full_20200730_final_lddUpdated.fits\",verbose=1,nocatalog=1" gdl -e "make_jsdc_script_simple,\"JMDC_full_20200730_final_lddUpdated.fits\",\"catalog2020.fits\",verbose=1" ---++ JSDC input catalog See procedure at /vobs/config/prepare_candidates/proc.sh This script generates the 2 input files in the vobs/config folder for the JSDC_BRIGHT (vobsascc_simbad_sptype.cfg) / JSDC_FAINT (vobsascc_simbad_no_sptype.cfg) input catalogs (candidates) used to run SearchCal scenarios and obtain the JSDC full databases (data + computations). ---+++ How to update the input catalogs ? Run proc.sh Overall description: - get both ASCC & SIMBAD full catalogs via cdsxmatch.u-strasbg.fr/QueryCat queries (vot) - crossmatch catalogs using radius = 2 as (all from 1) on J2000 coords (corrected by PM) + compute group size at 5 as in both catalogs (GROUP_SIZE) - produce input catalogs in SearchCal vobsCatalog format (ascii): * RAJ2000/DEJ2000, pmRA, pmDE (ASCC) * MAIN_ID, SP_TYPE, OTYPES (Simbad at 2as) * GROUP_SIZE (max GroupSize in both catalogs at 5as) - split the full ASCC in 2 lists (!NULL_SP_TYPE / NULL_SP_TYPE) (2017-04-14) * vobsascc_simbad_sptype.cfg: 494401 rows * vobsascc_simbad_no_sptype.cfg: 2006912 rows Comments: * ASCC is a catalog compilation (TYCHO2 + others) that contains many duplicates with 2as (tycho2 components or other known binaries ...) * Simbad coordinates (used by crossmatch) now use Gaia DR2 ones for 3M objects where SIMBAD retrieved the 'unique' GAIA object NOTE: these files were produced at 2017-04-14, not updated in 2020 as a cds-healpix-java bug make procedure to fail (simbad 11M objects): {{{ processing @ date: mardi 15 septembre 2020, 09:59:32 (UTC+0000) Params: Max Error(Number)/arcsec=5.0 Tuning: HEALPix k(Integer)=11 Binning rows for table 2............................................. Error: Hash value 13421764095 must be in [0, 12884901888[ }}} ---+++ How to run SearchCal scenarios ? * Server side (~bourgesl) * Publish results at * Run filter.sh ---++ JSDC 2020 generation ---++ -- %USERSIG{LaurentBourges - 2020-09-15}%
