/* ** ** 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 55904.753914 0.000625 0.86159 0.25850 1.00000 1 0.28502 0.05869 0.22669 0.04668 0.24557 0.05359 0.19535 0.04263 55904.755294 0.000755 0.69865 0.20019 0.96154 1 0.30173 0.05603 0.24167 0.04488 0.21080 0.04600 0.16800 0.03666 55904.757531 0.001482 0.61327 0.13514 0.96851 1 0.27305 0.03689 0.21789 0.02944 0.16745 0.02915 0.13362 0.02326 55904.821313 0.000654 0.92031 0.29057 0.97778 1 0.24248 0.05318 0.19443 0.04264 0.22316 0.05069 0.17912 0.04069 55904.822460 0.000494 1.29706 0.44579 1.00000 1 0.22436 0.05833 0.18062 0.04696 0.29101 0.06541 0.23413 0.05263 55904.823608 0.000654 0.71641 0.20975 0.97778 1 0.31671 0.05985 0.25455 0.04810 0.22689 0.05074 0.18182 0.04066 55904.825148 0.000886 0.66904 0.19564 1.00000 1 0.24280 0.04541 0.19527 0.03652 0.16244 0.03651 0.13050 0.02933 55904.826760 0.000726 1.07813 0.31053 0.98238 1 0.24192 0.05067 0.19490 0.04082 0.26083 0.05156 0.21012 0.04154
