EOVSA Catalog Design and VSO Integration D. Zarro 1 EOVSA Kickoff Meeting September 2012

Build on IDL Database  Heritage: IUE, UIT, SOHO/CDS, Hinode/EIS  IDL-based, with supporting routines in SSW  OS- and Platform-independent (Windows, Unix/Linux, Mac OS X ) 2

Catalog Design Considerations  What data products will be searched (images, spectra, lightcurves)?  What metadata will be stored in catalog (observing ids, engineering parameters)?  What metadata will be searchable (e.g. time, frequency)? 3

#items TL_ID I*4 Timeline ID from planning software OBSTITLE C*80 Observing program title TARGET C*40 Target of observation STUD_ACR C*40 Study Acronym OBS_DEC C*240 Description of observation OBS_NUM I*2 Sequential number of observation JOP_ID I*2 Joint Observing Program ID. EIS_SC C*120 Description of EIS science objective OBSERVER C*60 Name of chief observer DATE_OBS R*8 Date/time of beginning of observation DATE_END R*8 Date/time of end of observation NOAA_NUM I*2 NOAA Active Region Number (from planning software) NOAA_AR I*2 NOAA Active Region Number (calculated) SCI_OBJ C*80 Science objective XCEN R*4 Actual pointing of center of image in solar X YCEN R*4 Actual pointing of center of image in solar Y FOVX R*4 Width of field of view in solar X FOVY R*4 Width of field of view in solar Y DATE C*80 Date the FITS file was written FILENAME C*80 Name of FITS file study data was retrieved from. 4 Example EIS Catalog entries

 Archive of searchable data products  Catalog writer/updater  Catalog reader/browser 5 Catalog Requirements

Catalog Population Pipeline EOVSA Processed Data Archive SSW IDL EOVSA Catalog VSO Registry 6 Continuous process: 1.Extract metadata from data file headers. 2.Populate catalog with metadata. 3.Push catalog to SSW. 4.Pull search entries into VSO. => Search catalog via VSO clients and/or IDL directly.

 SSW/IDL database reader returns data structures with fields that match metadata entries 7 IDL> list_eis_main,’1-may-11’,’2-may-11’,obs ** Structure EIS_MAIN_LIST, 28 tags, length=304, data length=296: TL_ID LONG OBSTITLE STRING 'HOP 185. AR magnetism with SST. TARGET STRING 'Active Region ' OBS_DEC STRING 'Switch to returning AR on NE limb. JOIN_SB STRING 'E,S,X ' OBS_NUM INT 0 JOP_ID INT 185 STUDY_ID LONG 360' EIS_SC STRING 'UNKNOWN DATE_OBS DOUBLE e+09 DATE_END DOUBLE e+09 SCI_OBJ STRING 'AR XCEN FLOAT YCEN FLOAT FOVX FLOAT FOVY FLOAT DATE STRING ' FILENAME STRING 'eis_l0_ _ fits.gz

 VSO/IDL client returns selected metadata and file URL locations 8 IDL> files=vso_search('1-may-08','10-may-08',inst='eis',/url) Records Returned : SDAC_EIS : 206/206 _ _ fits.gz _ _ fits.gz _ _ fits.gz _ _ fits.gz
