/* ** ** 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 57150.510617 0.001046 0.68671 0.20137 1.00000 1 0.19918 0.03779 0.16174 0.03068 0.13678 0.03059 0.11111 0.02485 57150.512680 0.000988 0.75367 0.22611 1.00000 1 0.19222 0.03845 0.15625 0.03125 0.14487 0.03240 0.11765 0.02631 57150.514539 0.000872 0.77210 0.23444 1.00000 1 0.21085 0.04304 0.17143 0.03499 0.16280 0.03660 0.13267 0.02982 57150.516369 0.000959 0.84213 0.25932 0.98485 1 0.17859 0.03759 0.14476 0.03046 0.15040 0.03381 0.12246 0.02753 57150.518170 0.000842 0.71206 0.21074 0.98276 1 0.24168 0.04651 0.19637 0.03779 0.17209 0.03869 0.13965 0.03139 57150.520248 0.001235 0.55692 0.14595 0.95057 1 0.25029 0.03909 0.20247 0.03162 0.13939 0.02933 0.11287 0.02375
