/* ** ** 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 56725.926261 0.000793 0.27250 0.02177 0.98540 0 5.98548 0.22233 5.44961 0.20242 1.63101 0.11533 1.48395 0.10493 56725.927783 0.000729 0.30475 0.02472 0.98413 0 5.80988 0.22781 5.29946 0.20779 1.77055 0.12572 1.61509 0.11469 56725.929351 0.000839 0.25034 0.02008 0.99310 0 6.04185 0.21760 5.50032 0.19810 1.51255 0.10840 1.37643 0.09865 56725.930821 0.000631 0.33322 0.02728 0.99083 0 6.15829 0.25353 5.58371 0.22986 2.05207 0.14523 1.85929 0.13158 56725.932230 0.000778 0.26521 0.02131 0.98141 0 6.24279 0.22944 5.67843 0.20869 1.65563 0.11827 1.50559 0.10754 56725.933720 0.000712 0.28665 0.02336 0.99187 0 6.23021 0.23858 5.65537 0.21655 1.78588 0.12843 1.62028 0.11652 56725.935152 0.000720 0.30225 0.02467 1.00000 0 5.81758 0.22989 5.28278 0.20875 1.75839 0.12560 1.59629 0.11402 56725.936686 0.000813 0.26078 0.02088 0.98577 0 6.15615 0.22425 5.54097 0.20182 1.60540 0.11447 1.44556 0.10308
