These 128 FITS files are the two-year data from ACTPol and are the maps use to the results presented in Louis et al. (2016).
The maps presented are both the 4-way splits used to compute the power spectrum, and 1-way inverse-variance co-added field maps.
The maps are references using the following name format:
** I_src_free indicates calibrated T map with sources subtracted at the time-stream level [uK]
The temperature and polarization maps are calibrated with a single coefficient, which is measured for each field and reported in Louis et at. (2016). An extra polarization efficiency parameter is included (and let to vary) in the likelihood analysis and NOT considered here.
The label "1way" indicates the co-added maps, while 4way indicates the maps are part of the set of 4 splits.
1way maps (set='1way') also have components: ['risingscans_hits','settingscans_hits']
The beams used in Louis et al. (2016) are also presented on LAMBDA, and the resultant power spectra from the Louis et al. (2016) paper.
