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.

      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) has the
          radio appearance of an ultracompact HII region. Our position is
          slightly offset from the radio source to avoid foreground stars.
