This part of the spectrum is dominated by a series of strong, wide emission features commonly called the Unidentified Infrared Bands (UIR). The sampled area covers the inner Milky Way from l=-60° to +60° with a ten-degree step in longitude and nominal latitudes b=0°, ±1°. For each grid position the actual observed direction was selected from IRAS 100µm maps to minimize contamination by point sources and molecular clouds. Description: The dataset consists of 49 small raster maps made with the ISOPHOT-S spectrometer onboard the Infrared Space Observatory (ISO). This low-resolution (R∼60, Δλ∼0.1µm) instrument covers the wavelength range λ=2.5-11.6µm with a small gap at 4.9-5.8µm. Observations spanned a large part of the lifetime of ISO; the first dataset was recorded during revolution 81 (2/1996) and the last during revolution 840 (3/1998). ISO Target Dedicated Time (TDT) numbers for each observation are listed in table2. File Summary:

Note (1): Notes: a: Very high dark current. b: Has 7.7µm "ghost" band in the dark measurement. c: Shows evidence of point source contamination in one of the four pixels. This pixel was omitted from the average value calculation. d: Observed 7 months later than other G+30 points.
