File name: data_vec.dat
File description: Counts rates in used spin-angle bins (240-294 deg) for key ISN orbtis. Additionally provided are for each bin: count number, throughput correction [TC] factor, duration of observations, and subtracted Warm Breeze (WB) rate. Negative values of some count rates follow from subtraction of the Warm Breeze and backgrounds, but are consistent with zero if all uncertainties are taken into account.
File contents: orbit/arc, spin angle bin [deg], corrected count rate [1/s], counts [1], TC factor [1], duration of observation [s], WB rate [s].

File name: data_mat.dat
File description: Elements of the covariance matrix for all data. Matrix is symmetric. Element in i-th row (with header excluded) and j-th column correspond to covariance between count rate i-th and j-th given in file data_vec.dat in respective rows.
File contents: elements of covariance matrix.
