/* ** ** 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 58928.116652 0.000421 0.28568 0.07121 1.00000 1 4.22436 0.49640 1.01070 0.11874 1.20681 0.26529 0.28766 0.06324 58928.117640 0.000566 0.26683 0.06724 0.97436 1 3.26912 0.37966 0.79085 0.09184 0.87231 0.19507 0.21053 0.04708 58928.118686 0.000479 0.27414 0.06877 1.00000 1 3.79964 0.44735 0.91414 0.10762 1.04162 0.23074 0.25103 0.05560 58928.119775 0.000610 0.24023 0.05919 0.95238 1 3.57305 0.38586 0.86421 0.09332 0.85836 0.19011 0.20710 0.04587 58928.120995 0.000610 0.32247 0.08191 1.00000 1 2.53904 0.32286 0.61450 0.07814 0.81876 0.18003 0.19862 0.04367 58928.122114 0.000508 0.29780 0.07648 0.97143 1 3.27440 0.40286 0.78313 0.09634 0.97512 0.21980 0.23359 0.05264 58928.123203 0.000581 0.28836 0.07330 0.97500 1 2.93424 0.35464 0.71052 0.08588 0.84611 0.18920 0.20513 0.04587 58928.124249 0.000465 0.30042 0.07700 1.00000 1 3.45403 0.43262 0.83124 0.10410 1.03766 0.23204 0.25000 0.05590 58928.125266 0.000552 0.30777 0.07740 0.97368 1 3.03261 0.37032 0.73044 0.08919 0.93334 0.20519 0.22546 0.04957 58928.126442 0.000625 0.32392 0.07231 0.97871 1 3.24804 0.36747 0.79131 0.08951 1.05211 0.20249 0.25663 0.04939
