/* ** ** 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 56537.398984 0.000964 0.46057 0.12588 0.96697 0 0.35834 0.05561 0.26908 0.04176 0.16504 0.03713 0.12372 0.02783 56537.401010 0.001062 0.44053 0.11583 0.95913 0 0.36331 0.05328 0.27081 0.03971 0.16005 0.03493 0.11952 0.02608 56537.402705 0.000634 0.88108 0.27701 0.96804 0 0.28061 0.06083 0.21063 0.04565 0.24724 0.05630 0.18577 0.04230 56537.404054 0.000715 0.91535 0.28846 0.99190 0 0.23811 0.05287 0.17839 0.03961 0.21795 0.04874 0.16354 0.03657 56537.405720 0.000952 0.47987 0.13262 0.96049 0 0.34652 0.05496 0.26113 0.04141 0.16629 0.03763 0.12535 0.02837 56537.408189 0.001516 0.67114 0.14172 0.95992 0 0.29745 0.03983 0.22392 0.02999 0.19963 0.03259 0.15044 0.02456
