Combining our results with the available Multiband Imaging Photometer for Spitzer (MIPS) 24µm survey of this area, we produce a catalog of 150 16µm sources brighter than 0.18mJy (3σ) for which we derive measures or limits on the 16µm/24µm colors. Such colors are especially useful in determining redshifts for sources whose mid-infrared spectra contain strong emission or absorption features that characterize these colors as a function of redshift. Description: We observed 57 positions in the Bootes field during two different periods using the IRS on Spitzer. The total field of view of a blue peak-up image in both nod positions is 50pix x 55pix. Since the pixel size of the IRS Short-Low module is 1.8"x1.8", the field of view is 2.475arcmin2. The total area observed is 0.0392°2, which is 230 times smaller than the total area of the Bootes survey imaged at 24µm with MIPS. The observations were obtained between 2004 August 27 and September 2, as well as between 2004 November 11 and 17, with exposure times of ∼240s, resulting in a median 1σ depth of ∼0.06mJy at 16µm.

Note (1): SST16 source name derives from discovery with the IRS PU 16µm images; coordinates listed are in J2000; 16µm positions with typical 3σ uncertainty of ±1.2"; sources with an optical counterpart will also appear in NDWFS catalogs with prefix NDWFS and the optical source position; sources with a MIPS 24µm counterpart will also appear in MIPS catalog. Note (2): Upper limits for 24µm sources are assumed to be 0.18mJy. Note (3): Optical magnitudes are Mag-Auto from NDWFS DR3, available at http://www.noao.edu/noao/noaodeep/; the NOAO filters characteristics are available at http://www.noao.edu/kpno/mosaic/filters/
