/* ** ** 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 59652.241133 0.000697 0.31926 0.02625 0.97510 0 8.05884 0.32845 5.28043 0.21515 2.57290 0.18374 1.69181 0.12080 59652.242629 0.000799 0.25013 0.02035 0.98913 0 8.64703 0.31381 5.72876 0.20789 2.16288 0.15753 1.43366 0.10439 59652.244136 0.000709 0.29576 0.02427 0.97551 0 8.44929 0.33149 5.58948 0.21925 2.49898 0.18014 1.65055 0.11901 59652.245531 0.000686 0.29508 0.02393 0.96624 0 8.94808 0.34358 5.88457 0.22587 2.64040 0.18856 1.73613 0.12396 59652.246972 0.000755 0.28571 0.02316 0.96935 0 8.31791 0.31947 5.50224 0.21132 2.37650 0.16968 1.57144 0.11220 59652.248517 0.000790 0.26349 0.02143 0.97802 0 8.70199 0.32596 5.58866 0.20924 2.29290 0.16548 1.47746 0.10653 59652.250042 0.000735 0.28178 0.02285 0.97244 0 8.91683 0.33904 5.70322 0.21682 2.51255 0.18000 1.60544 0.11501 59652.251764 0.000987 0.28284 0.02008 0.97067 0 8.63085 0.28707 5.55085 0.18457 2.44119 0.15311 1.56704 0.09826
