Spitzer First Look Survey (FLS) -- NOAO Extragalactic -- R
You can get a close-up map of a region by clicking on any area in red on the above image, or by typing a coordinate below.
On behalf of the Spitzer Space Telescope user community, the Spitzer Science Center (SSC) is conducting a First-Look Survey (FLS). The extragalactic component of the FLS was executed on Spitzer in December, 2003.
The National Optical Astronomy Observatory (NOAO) provided four nights of Director's Discretionary time for an R-band survey with the MOSAIC camera on the Kitt Peak 4m telescope to support the FLS. Approximately 30 pointings with MOSAIC were obtained covering the entire FLS region centered at J1718+5930. They are outlined in figure 1 and in the image above.
If you publish results based on these data, please use this paper reference and acknowledgment.
NOTE: These data are also available from the Spitzer Science Center and the NOAO Science Archive. The headers of the FITS files available here have minor changes to make them fully FITS compliant; the science content is unchanged. Details of the header changes are here.
The available images are represented as red overlays on the 2MASS background sky mosaic image above. SExtractor catalog sources, bad pixel and exposure maps are available on the search results pages, for the associated images. Either type in a coordinate or click on any red region to get a close-up of the area; the size of the search is adjustable.
Also available are FLS_MAIN_R image "cutouts" 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.
