From roc@ventusTue Aug 10 16:36:54 1999 Date: Fri, 30 Jul 1999 16:58:16 -0700 (PDT) From: Roc Cutri To: 2mass-staff@ventus.ipac.caltech.edu Cc: roc@ventus.ipac.caltech.edu Subject: additional tiles removed from fall 99 release Because of a bookkeeping error, several tiles were left in the OPS database that were identified as bad during preparation for the Spring 99 data release. Since they remained in the OPS DB, they were inadvertantly extracted for inclusion in the Fall 99 data release. Those tiles have been identified and removed from both the OPS and Release Working DB's. The offending scans were reset to quality zero in the Survey Tile database when they were first identified in March, and one has already been reobserved (although at quality=2). In addition to the 3 tiles that were rescored with quality = 0, 2 more tiles will be removed from the Fall 99 release list and the Release Working DB's (not the OPS DB) because of contiguity requirements having lost one of the bad tiles. The tiles that are being removed are: 970610 n 102 11070 - RA Slip 970913 n 129 6196 - J-quadrant drop-out 970918 n 026 8417 - J-quadrant drop-out 970918 n 024 8415 - Contiguity 970918 n 025 8416 - Contiguity A revised list of the candidate tiles for the Fall 99 release can be found in ~roc/fall99.final.datescanh.list Roc From roc@ventusTue Aug 10 16:37:45 1999 Date: Tue, 10 Aug 1999 14:54:16 -0700 (PDT) From: Roc Cutri To: 2mass-staff@ventus.ipac.caltech.edu, irsa-staff@ventus.ipac.caltech.edu Cc: Roc Cutri Subject: Tiles to be removed from Fall99 list Two more tiles will be removed from the Fall 99 candidate list. They are tiles 24491 and 24492 (scans 043 and 044 from 990312n). They were incorrectly assigned quality 10 in the operational database. Their correct quality score was 4. The correct score is present in the QA review and in the survey master tile database. The sources from this tile will be removed from the Release Working Tables (tmasss), and the quality values have been corrected in the Scan Information table in the OPS database. The Scan Selection for the Fall/Winter 1999 Data Release page has been updated to reflect these changes at: http://spider.ipac.caltech.edu/staff/roc/2mass/catalogs/criteria/fall99.scans.html Roc From roc@ventusThu Dec 16 14:42:34 1999 Date: Wed, 15 Dec 1999 15:36:50 -0800 (PST) From: Roc Cutri To: Richard.W.Capps@jpl.nasa.gov, jmc@astro.caltech.edu, huchra@cfa.harvard.edu, jhe@noao.edu, liebert@as.arizona.edu, dgm@nofs.navy.mil, price@plh.af.mil, seitzer@astro.lsa.umich.edu, schneide@messier.astro.umass.edu, skrutski@astro.umass.edu, stiening@cannon.astro.umass.edu, weinberg@owl.astro.umass.edu, Eric Howard , John Gizis , 2mass-staff@ventus.ipac.caltech.edu, irsa-staff@ventus.ipac.caltech.edu Cc: Roc Cutri Subject: Fall/Winter Release Catalog Tables Update 1. Anomalous noise scans All sources and scan information from the 37 scans with anomalously high point source noise are now being removed from the Fall/Winter Release Working Databases and Draft Catalogs accessible via IRSA (in tmasss). The affected scans are described in: http://spider.ipac.caltech.edu/staff/roc/2mass/catalogs/fall99/analysis/pnoise.html You should remove any reference to those scans/tiles from all internal and external files you maintain regarding the next data release. The number of rows in each table reported in CATSCAN should automatically update tonight. Note that sources from the 37 tiles will be removed from Executive Summary PSC files in few days. For reference, the installments of the Summary PSC that contain the scans to be removed are: fall99pscshort9.tbl fall99pscshort16.tbl fall99pscshort19b.tbl fall99pscshort23.tbl 2. Saturated R1 magnitudes As with the Spring 99 Release Point Source Catalog, the magnitudes for all PSC sources that are saturated in R1 (rd_flg=3) are now being set to -99.999. Only magnitudes in the saturated bands are being changed. The Team made this decision for the last release because there is valid uniform brightness information for those sources. Please let me know if you have any questions.
