Addition of one data product to the post-bcd products listing in the IRS data products description.
In the IRS AOT Example #1 (SOM v4.0, section 7.2.4.1), the units of all line fluxes were inadvertantly given as W cm^-2 instead of the correct units of W m^-2. Please change all flux units in this example to W m^-2 (you do NOT have to change any of the numbers). This will be corrected in the next release version of the SOM, and has already been corrected in the online copy of the examples.
Slightly modified sensitivity and saturation web pages; the information is the same as was released in the SOM.
Papers and talks from 2004 Atlanta AAS - IRS ones included or coming soon
