1. Re-processed IRS SL and LH data
--------------------------------------------------
This is to inform users that a small subset of the IRS Long-High (LH) and
Short-Low (SL) data had improper calibration files applied to them in the
S15 pipelines.

The affected IRS LH (channel 3) data had incorrect dark calibration
files subtracted in the S15 pipelines. Instead of campaign-dependent
LH darks, these data were reduced in the BCD threads with a multi-
campaign dark. This may result in more rogue pixels being evident in your
LH data taken during these periods.  The affected LH data were taken in
IRS campaigns 29 through 34 and in campaign 36 as follows:

IRS-29 (IRSX006300):  3-22 March 2006
IRS-30 (IRSX006500):  15-26 April 2006
IRS-31 (IRSX006700):  10-31 May 2006
IRS-32 (IRSX006800):  18 June - 5 July 2006
IRS-33 (IRSX007200):  23 July - 7 August 2006
IRS-33.3 (IRSX009600):  31 August 2006 (Post-Anomaly Science Verification)
IRS-34 (IRSX007400):  5-18 September 2006
IRS-36 (IRSX007600):  8-21 November 2006

The affected IRS SL (channel 0) data were processed using an
outdated mask file used to estimate (and remove) the peakup stray light.
Observations in SL order 1 may be affected when a bright source is
present in SL order 2.  The effect will be a dark "banding" in the
order 1 spectrum at approximately 10 microns (rows 82-90).  The affected
SL data were taken in IRS campaigns 38-41 as follows:

IRS-38 (IRSX007800):  23 January - 14 February 2007
IRS-39 (IRSX008000):  7-28 March 2007
IRS-40 (IRSX008100):  15 April - 6 May 2007
IRS-41 (IRSX008200):  7-27 June 2007

The LH and SL data described above have been re-processed with the correct
calibration files in the S16.1.0 IRS pipelines.  These data are now
available through Leopard.


2. 2008 Spitzer Postdoctoral Fellowship Program Guidelines
--------------------------------------------------
The SSC would like to announce the release of the Application Guidelines
for the 2008 Spitzer Space Telescope Postdoctoral Fellowship Program.  All
application materials are due on November 1, 2007.  A web-based cover
sheet must be filled out online with the application materials
(https://cat.ipac.caltech.edu/Fellows/application.html).
Please read and follow the instructions in the application guidelines.


NOTE: Registration for the 2007 August Data Analysis Workshop is now
closed.  We hope to see you next time.

REMINDER: The Cycle-5 Call for Proposals will be released on 2007 August
15, with proposals due on November 16. Cycle-5 will be the last cryogenic
observing cycle.
