/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 56507.885773 0.000475 0.18259 0.02815 1.00000 0 3.92055 0.24040 3.34440 0.20507 0.71587 0.10124 0.61077 0.08638 56507.886684 0.000437 0.25186 0.04073 0.95364 0 3.16289 0.22572 2.70041 0.19271 0.79660 0.11561 0.68013 0.09868 56507.887506 0.000385 0.26777 0.04276 0.97744 0 3.35132 0.24860 2.87641 0.21337 0.89739 0.12691 0.77051 0.10897 56507.888250 0.000359 0.26297 0.04204 0.97581 0 3.65174 0.26573 3.12996 0.22776 0.96031 0.13667 0.82322 0.11716 56507.888982 0.000373 0.25109 0.04034 0.97674 0 3.68501 0.26570 3.15844 0.22773 0.92528 0.13285 0.79319 0.11389 56507.889786 0.000431 0.23424 0.03713 0.93960 0 3.52117 0.23912 3.02034 0.20511 0.82480 0.11814 0.70752 0.10134 56507.890779 0.000561 0.16958 0.02661 0.98969 0 3.51271 0.21017 3.00788 0.17996 0.59569 0.08643 0.51010 0.07401 56507.891771 0.000431 0.14022 0.02785 0.97987 0 3.31387 0.23383 2.83843 0.20028 0.46467 0.08629 0.39792 0.07389 56507.892686 0.000483 0.19261 0.02993 0.97006 0 3.72533 0.23240 3.19275 0.19917 0.71754 0.10212 0.61488 0.08751 56507.893594 0.000425 0.23900 0.03770 0.98639 0 3.39279 0.23693 2.88825 0.20167 0.81086 0.11468 0.69081 0.09769 56507.894393 0.000373 0.27081 0.04356 0.97674 0 3.42059 0.25632 2.91813 0.21866 0.92632 0.13184 0.79055 0.11251 56507.895096 0.000330 0.33743 0.05493 0.97368 0 3.17652 0.25895 2.71681 0.22147 1.07186 0.15103 0.91543 0.12899 56507.895866 0.000440 0.23837 0.03778 0.97368 0 3.29573 0.22992 2.81950 0.19669 0.78559 0.11181 0.67304 0.09579 56507.896682 0.000376 0.28298 0.04540 0.96154 0 3.33223 0.25224 2.83758 0.21475 0.94297 0.13337 0.80133 0.11333 56507.897827 0.000770 0.20144 0.02446 0.98496 0 3.71435 0.18468 3.14569 0.15639 0.74821 0.08290 0.63379 0.07021
