ABSTRACT
INTRODUCTION
a. overview of 2mass project (what is it, numbers, scientific objectives)
b. Extended Sources; brief discussion of some of the science projects geared towards 2MASS galaxies & ext. srcs; introduce or reiterate level-1 specs
c. data release and overview of data covered in this paper
d. GIVE bullet summary (ala T.Chester)
e. outline objectives of paper and forecast future papers to come
DATA
review data products (relevant to galaxies) and define 2MASS data type (e.g., what is a scan/tile; what is a coadd; postage stamp, etc).
**briefly** introduce catalog parameters (this is so long and complex
that an entire chapter needs to be devoted to this)
tabulate data set introduced in paper; discuss/outline "mini-release data and march'99 incremental release
might be a good point to flash some real data (one or two coadds and
some postage stamps) for flavor
STAR-GALAXY DISCRIMINATION & ALGORITHMS
overview of work in the field, including those of the
POSSI people (odewahn) and the POSSII people (weir);
traditional X-Y "cart" methods, decisions trees and
neural nets.
2mass source detection and types of things detected
(stars, multiple stars, extra-galac pt srcs, galaxies, artifacts)
introduce & define our primary discriminents
("sh","wsh" & "r23"). Here we need to discuss stellar
ridges and atmos-seeing in general.
briefly introduce other star-galaxy discriminators
introduce the use of oblique decision trees and how we
employ them
summarize our completeness and reliability (later we will
give further proof with galaxy counts) after applying
simple "cart" thresholds (i.e., "sh" and "wsh") and
OBDTs.
future direction (different DTs and auto-classifiers)
EXTENDED SOURCE CATALOG
the objective of this section is to discuss/introduce the
detailed output of GALWORKS (mostly mags). a table might be sufficient
with some additional descripts or notes. the table might look very
similar to the one generated by the DB (or catscan ... whatever).
we might also delve more deeply into some of the trickier parameters
of GALWORKS (like ellipse fitting)
highlight some of the more "important" forms of photometry
(i.e., impose our own personal bias on what mags people should
be looking at): fixed circ r=7 and K-fid isophotal.
FIRST RESULTS
a. Galaxy Counts & Completeness (with reliability relevant to faintest
bins); how do counts stack up with previous work and with pencil
beam studies; can we help clarify the great debate: no evolution,
modest evolution, copious evolution (the answer is: not likely, since
the models only begin to diverge at our faintest mag bins)
b. Colors (& discuss reddening due to redshift)
DISCUSSION
given the results presented above, what projections can we make
for the remaining survey (total number of gals, reliability,
artifact rate, etc)
prospects of cross-matching with other cats (SDSS, POSSII)
large scale structure and introduction of the 2MASS cluster catalog
(and any other projects now underway like the Schneider/Hucra
KEY project)
