/* ** ** 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 59875.840066 0.000988 0.55473 0.15537 0.97059 1 0.47061 0.07845 0.21818 0.03636 0.26106 0.05876 0.12048 0.02711 59875.842172 0.001118 0.44826 0.12203 1.00000 1 0.50419 0.07828 0.23199 0.03602 0.22601 0.05054 0.10390 0.02323 59875.845252 0.001961 0.42898 0.08977 0.98295 1 0.49765 0.05778 0.23177 0.02690 0.21348 0.03717 0.09947 0.01732 59876.048357 0.001031 0.37861 0.10075 0.97183 1 0.64572 0.09004 0.30439 0.04243 0.24447 0.05541 0.11447 0.02595 59876.050725 0.001336 0.55941 0.12247 0.98722 1 0.54608 0.07143 0.25872 0.03384 0.30548 0.05363 0.14422 0.02531 59876.781986 0.000610 0.61361 0.17715 0.97619 1 0.66260 0.12098 0.31579 0.05766 0.40658 0.09092 0.19512 0.04363 59876.783410 0.000813 0.74500 0.21981 0.98214 1 0.41333 0.07956 0.19636 0.03779 0.30793 0.06886 0.14545 0.03252 59876.785138 0.000915 0.49287 0.13499 0.98413 1 0.56356 0.08912 0.26230 0.04147 0.27776 0.06212 0.12903 0.02885 59876.787811 0.001758 0.54163 0.10894 0.99298 1 0.51867 0.06306 0.23815 0.02894 0.28093 0.04501 0.12984 0.02079
