/* ** ** 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 56535.255047 0.000524 0.85367 0.26165 0.97790 0 0.35303 0.07399 0.26505 0.05555 0.30137 0.06739 0.22637 0.05062 56535.256268 0.000697 0.60642 0.17279 0.96680 0 0.37416 0.06607 0.28232 0.04986 0.22690 0.05074 0.17196 0.03845 56535.257625 0.000660 0.61334 0.17508 0.97807 0 0.38853 0.06894 0.29304 0.05199 0.23830 0.05329 0.17967 0.04018 56535.258962 0.000677 0.70183 0.20682 0.95299 0 0.33936 0.06513 0.25479 0.04890 0.23818 0.05326 0.17967 0.04018 56535.260342 0.000703 0.72670 0.21084 0.97119 0 0.32190 0.06109 0.24397 0.04630 0.23393 0.05133 0.17732 0.03891 56535.261893 0.000842 0.47978 0.13141 0.97938 0 0.39028 0.06172 0.29139 0.04607 0.18725 0.04188 0.14058 0.03144 56535.263655 0.000920 0.94280 0.25215 0.96541 0 0.24822 0.04610 0.18741 0.03480 0.23402 0.04504 0.17619 0.03391
