README for FLS Ecliptic Plane Component.

The First Look Survey IRAC data comprises 6 AORs. 3 for the 0 degree
ecliptic latitude field (6095104,6095360, 6095616), and 3 for the +5
degree ecliptic latitude field (6095872,6096128,6096384). Both fields
are approximately 0.13 sq. degrees in area. In both cases the field
center (given in the table below) and mapping pattern (2x10 frames)
are identical for all three AORs within a given field set, modulo the
random placement of individual frames due to the dither pattern. For
each latitude field we therefore have 3 time-resolved observations of
that same field, separated by approximately 70 minutes. This technique
allows us to search for moving targets by observing which targets are
found at the same coordinates in all three observations, and which
ones move as a function of time. In the IRAC data, asteroids are most
detectable in the 8um frames. Individual pipeline processes frames can
be found in the bcd directories for each AOR. Mosaics of the entire
field at each wavelength are available in the pbcd directories.

A detailed description of the observing rationale and plan can be found at:

http://ssc.spitzer.caltech.edu/fls/eclip

The preliminary analysis of this data, including thermal measurements
for known asteroids in the fields, and number counts, can be found at:

http://ssc.spitzer.caltech.edu/fls/eclip/2feb04rept.pdf

The AORs as executed can be viewed within SPOT using the View Progra
capability under the File menu, and using Program ID (PID) 98.

Data in this release replaces any previous releases.

We have created a status page

        http://ssc.spitzer.caltech.edu/archanaly/status

that shows the processing and archiving status for all of the
instrument campaigns. We will be updating this frequently as we
populate the archive; check there for release status of observations
for this, and other, Spitzer programs.

Briefly, data is PROCESSED through the pipelines, then ARCHIVED and
made available through the interface; First Look Survey, Legacy, and
Early Release Observation data are also staged to the Popular Products
web site. It is much faster to get the public data from the website
than having to query it out of the archive yourself.

Recommended download strategy:

   a.  Download the Spitzer Pride software
        (http://ssc.spitzer.caltech.edu/propkit/spot/)
   b.  Install Spitzer Pride
   c.  Start Leopard
   d.  Select Popular Products Query from the File menu
       and choose the data sets you want
   e.  Select Download Selections from the file menu and let
       the Leopard Subscriber manage the data download from the
       Popular Products website.
