/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56235.647756 0.000581 0.72489 0.21786 1.00000 1 0.57059 0.11253 0.27235 0.05369 0.41361 0.09380 0.19746 0.04476 56235.649049 0.000712 0.74738 0.21496 0.93878 1 0.49908 0.09268 0.24167 0.04488 0.37301 0.08192 0.18150 0.03986 56235.650807 0.001046 0.56425 0.15759 0.97222 1 0.41479 0.06940 0.20210 0.03381 0.23404 0.05234 0.11429 0.02556 56235.652608 0.000755 1.12648 0.36330 0.98077 1 0.30156 0.07161 0.14590 0.03465 0.33970 0.07413 0.16471 0.03594 56235.654205 0.000842 0.65212 0.18929 0.96552 1 0.45111 0.08348 0.21940 0.04061 0.29417 0.06578 0.14286 0.03194 56235.655832 0.000784 0.76154 0.22703 0.94444 1 0.42648 0.08408 0.20698 0.04081 0.32478 0.07263 0.15686 0.03508 56235.658156 0.001540 0.53145 0.11020 0.99976 1 0.52664 0.06496 0.25582 0.03155 0.27988 0.04665 0.13588 0.02265
