GLIMPSE3D Source Lists Data Release for Six Areas - July 2008

=====================================================================
1. Overview
=====================================================================

This GLIMPSE3D source list data release is comprised of IPAC Tables of
the GLIMPSE3D Catalog and Archive for 6 ~2 deg x 2 deg areas 
centered at about

  (1 epoch; 2 visits) 
  l=18.5 deg,  b=+2 deg    
  l=18.5 deg,  b=-2 deg    
  l=25 deg,    b=+2 deg 
  l=25 deg,    b=-2 deg 
  l=30 deg,    b=+2 deg
  l=30 deg,    b=-2 deg

SSC pipeline processing version S16.1 was used in these datasets.
The highly reliable GLIMPSE3D Catalog (GLM3DC) consists of point sources 
that are detected at least twice in one band and at least once
in an adjacent band and a S/N > 5 cut for the band with the two
detections. There are also faint and bright flux limits on the
Catalog entries. The more complete Archive (GLM3DA) has less stringent
criteria, namely two detections in any bands, those detections
having a S/N > 5. The IRAC data were bandmerged with the 2MASS All-Sky
Point Source Catalog. See the GLIMPSE3D v1.1 Data Products & Data Delivery
document for more details.

2. Files in the GLIMPSE3D July 2008 Source Lists Release.
=====================================================================

A. GLIMPSE3D_source_lists_jul2008.README - This file. 

B. Catalog & Archive Files in IPAC Table Format

   There is one Catalog and one Archive file for each of the six areas.
   Thus there are 6 Catalog IPAC table files and 6 Archive IPAC table files.
   The Catalog and Archive files have the same format.

C. Data Dictionary for IPAC Tables and a Notes file with basic information about 
   some of the fields in the source list entry.

   GLM3DC.tbl.dd - Data Dictionary for the Catalog IPAC Tables
   GLM3DA.tbl.dd - Data Dictionary for the Archive IPAC Tables 
                   (exactly the same as GLM3DC.tbl.dd)

   GLIMPSE3D.notes - Notes on the source designation, close source flag, source quality 
     flag and flux calculation method flag used in the source lists.

   The IPAC Table validation tool (http://irsa.ipac.caltech.edu/applications/TblReformat/)
   was successfully run on some of the GLM3DA and GLM3DC IPAC Tables.

D. Documentation 

   The GLIMPSE3D v1.1 Data Release document (07/24/08) applies to these datasets.
   pdf and ps versions of the document are on available (glimpse3d_dataprod_v1.1.pdf
   and glimpse3d_dataprod_v1.1.ps).

   Other existing documentation includes the GLIMPSEI and GLIMPSEII Data Products and Quality
   Assurance Documents and a document describing in detail our point source photometry
   steps. See
     http://www.astro.wisc.edu/glimpse/docs.html

3. Miscellaneous Information
=====================================================================

A. Due to the nature of the survey mapping, there are areas outside of
   the nominal survey region that were observed (and may have incomplete coverage). 
   We provide whatever sources that were detected and pass our source list criteria
   from outside the nominal survey area.

B. There is a small amount of overlapping area between the GLIMPSEI and GLIMPSE3D surveys.
   Only the GLIMPSE3D data is presented in this data delivery.
