This page provides data products from the first SPT data release, described in detail in Schaffer et al. 2011, ApJ, 743, 90. This data release provides maps and auxiliary files for observations of the approximately 95 square degree ra5h30dec-55 field observed by SPT in the 2008 season with the 150 GHz and 220 GHz observing bands. The data release includes maps in both bands, prepared with two variations of filtering and projection. Map pixel weights, noise PSDs, and filter transfer functions are provided for each map. Beam functions and spectral bandpass functions for the 2008 SPT instrument are also provided.

If you have any questions regarding this data set or its use, please contact Kathryn Schaffer (kschaf2_at_saic_edu) or Tom Crawford (tcrawfor_at_kicp_uchicago_edu).

Below are links to FITS files containing SPT maps of the ra5h30dec-55 field observed in the 2008 season. These maps are described in detail in Schaffer et al. 2011, ApJ, 743, 90. Auxiliary files, instrument beams, and spectral bandpass functions are necessary for interpreting the maps. These files are included further below.

Maps:
Maps of the ra5h30dec-55 field in the 150 GHz and 220 GHz bands, presented in the Sanson-Flamsteed projection with bright point sources masked during data filtering.

Maps of the ra5h30dec-55 field in the 150 GHz and 220 GHz bands, presented in the oblique Lambert equal-area azimuthal projection with bright point sources not masked during data filtering.
