/* ** ** 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 56631.885273 0.000872 0.87182 0.26772 0.98333 1 0.18842 0.03966 0.15457 0.03253 0.16427 0.03673 0.13559 0.03032 56631.887132 0.000988 0.48964 0.13480 1.00000 1 0.29349 0.04713 0.23938 0.03844 0.14370 0.03214 0.11765 0.02631 56631.889282 0.001162 0.55998 0.15697 0.97500 1 0.22716 0.03840 0.18421 0.03114 0.12720 0.02844 0.10257 0.02293 56631.890967 0.000523 1.71186 0.61951 1.00000 1 0.16865 0.04869 0.13714 0.03959 0.28870 0.06300 0.23334 0.05092 56631.892477 0.000988 0.67956 0.19315 0.97059 1 0.22802 0.04152 0.18544 0.03377 0.15495 0.03381 0.12727 0.02777 56631.894990 0.001525 0.64718 0.16121 0.96309 1 0.20176 0.03190 0.16495 0.02608 0.13058 0.02513 0.10680 0.02055
