Presentation Transcript

  1. SourceLists & AssociateLists • Parallel Tables • External SourceLists • CombinedLists • SourceLinks • New Developments / Problems

  2. Parallel Tables • Oracle Table limit < 1000 columns • Better for external SourceLists • Easier for DB tuning and table statistics • Space saving on other nodes (DB links)‏

  3. External SourceLists • USNO A2.0, # 526.280.881 (100%)‏ • SDSS PhotoObjAll-DR5, # 354.254.163 (29%)‏ • SDSS Photoz-DR5, # 354.188.961 (29%)‏ • SDSS SpecObjAll-DR5, # 1.048.960 (19%)‏ • UKIDSS lasSource-DR3, # 36.250.945 (85%)‏ • 2MASS PSC, # 470.992.970 (0%)‏ • 2MASS XSC, # 1.647.599 (0%)‏

  4. CombinedList • Not a Class, but a set of functions • All operations on DataBase level • AssociateList  Single Source Catalogue • AID  SID • filters='MAG_1:#849,MAG_2:#850'

  5. CombinedList

  6. CombinedList Estimation: 100.000.000 sources in 4 days by 100,000 chunks

  7. SourceLink • Required for Individual Source Processing (i.e. for Galfit, Galphot)‏ • Provides a pointer to a Source in a SourceList

  8. New Developments / Problems • Associate Large SourceLists • Maximum number of SourceLists to Associate should be increased • Problems with HTM software • Mosaic AssociateList • Combine AssociateLists • Import/Export SL from/to XML
