Spitzer First Look Survey (FLS) Overview
FLS Overview FLS Primary Data Access FLS Cutouts IRSA Catalog Search Tool: FLS


The Spitzer First Look Survey (FLS) was the initial Director's Discretionary Time program executed on the observatory. The Extragalactic First Look Survey is composed of 4 square degrees of imaging with MIPS and IRAC centered at J1718+5930. The Galactic First Look Survey spent 36 hours mapping regions of the Milky Way, with the goal of characterizing cirrus and source counts in different Galactic environments. The Ecliptic First Look Survey concentrated on two 0.13 square deg fields at a solar elongation of 115 degrees and ecliptic latitudes (b) of 0 degrees and +5 degrees.
