Abstract:
We present Spitzer IRS spectra (R∼600, 10-38um) of 38 positions in
the Galactic center, all at the same Galactic longitude and spanning
±0.3° in latitude. Our positions include the Arches Cluster, the
Arched Filaments, regions near the Quintuplet Cluster, the "Bubble"
lying along the same line of sight as the molecular cloud G0.11-0.11,
and the diffuse interstellar gas along the line of sight at higher
Galactic latitudes.
Description:
We observed the GC region with the Infrared Spectrograph (IRS) on
Spitzer with the Short-High (SH, 10-19.5um) and Long-High
(LH, 19.5-38um) modules on 2005 March 21-23.

Note (1): Notes as follows:
a = Positions whose values of tau9.6 were increased to produce the
minimum [SIII] 18.7/33.5um line ratio after correction for extinction.
b = This maser source (Guesten and Downes, 1983A&A...117..343G 1983A&A...117..343G) has the
radio appearance of an ultracompact HII region. Our position is
slightly offset from the radio source to avoid foreground stars.
