We survey 150 arcmin2 in each of the two GOODS fields (North and South), to an average 3σ depth of 40 and 65uJy, respectively. We detect ∼1300 sources in both fields combined. We validate the photometry using the 3-24um spectral energy distribution of stars in the fields compared to Spitzer spectroscopic templates. Comparison with ISOCAM and AKARI observations in the same fields shows reasonable agreement, though the uncertainties are large. We provide a catalog of photometry, with sources cross-correlated with available Spitzer, Chandra, and Hubble Space Telescope data. Galaxy number counts show good agreement with previous results from ISOCAM and AKARI with improved uncertainties. Description: Data were taken in two general observer Spitzer programs: GO-3661, observing GOODS-South in Cycle 1, and GO-20599, observing GOODS-North in Cycle 2. The 16µm fluxes were detected with the Spitzer peak-up imaging (PUI) capability offered by the the Infrared Spectrometer (IRS). The Si:As detector was similar to that used in the 24µm channel of the MIPS instrument; in 10 minutes of observation, the PUI achieved 5σ depths of ∼45µJy. File Summary:

Note (4): Ratio of aperture flux in 6:2 pixel radii. Blanks indicate NaN values. Objects which are point sources should fall in the range of 2-3. Note (5): Quality Flag is assigned Bitwise (Q=Σ2b), where b means: 0 = included in catalog 1 = more than one 16 micron source within 5.4 arcsec; possible confusion 2 = source concentration differs from that expected for point source 3 = S/N ratio <5, but coverage indicates it should be higher 4 = sources with coverage of two exposures instead of three For example, an object with a flag value of 19 would indicate that Bits 0, 1, and 4 had been set because: (Bit 0) the object was included in the catalog; (Bit 1) the measurement of the object may suffer from confusion due to a close 16um neighbor; and (Bit 4) the object had a coverage of only two exposures.
