ELFLock Spitzer Data
You can get a close-up map of a region by clicking on the above image, or by typing a coordinate below.

The Eureka LBNL Far-IR Lockman Hole (ELFLock) maps are intended to measure the Far-IR background radiation with 160-micron observations from the Multiband Imaging Photometer for Spitzer (MIPS). The download gives the largest contiguous low-cirrus 160 micron far-infrared map made with Spitzer data, covering 8.5 square degrees. It also differs from standard Spitzer-processed mosaic maps in that the background information is preserved, where it is normally removed by median filtering (for point-source studies).

Download the entire map (5 MB) by clicking on the image above. "Cutouts" of the map are also available using IRSA's Cutouts Service, which is a general tool to create single or multiple small FITS (and JPEGs) image cutouts of datasets archived at IRSA.

The flux units are MJy/Sr and the pixel size is 15.9". Pixels without data have flux=0.0.

Grossan, B., & Smoot, G. F. 2007, A&A describe the maps, reductions and validation procedures. The map is composed of BCD data from S16 processing of data sets with these Spitzer Astronomical Observation Requests (AORs).
