/* ** ** 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 59647.129373 0.000602 0.27129 0.02232 0.98077 0 7.87169 0.29882 7.06189 0.26811 2.13553 0.15590 1.91516 0.13983 59647.130640 0.000666 0.27514 0.02238 0.97826 0 7.16252 0.27048 6.40316 0.24177 1.97068 0.14200 1.76009 0.12681 59647.131963 0.000657 0.25639 0.02074 0.97357 0 7.82035 0.28506 6.95949 0.25367 2.00502 0.14484 1.78289 0.12878 59647.133375 0.000755 0.24490 0.01958 0.98851 0 7.21788 0.25489 6.34608 0.22411 1.76767 0.12683 1.55396 0.11149 59647.134822 0.000692 0.24735 0.02007 0.97071 0 7.64729 0.27450 6.82655 0.24506 1.89156 0.13761 1.68880 0.12286 59647.136112 0.000599 0.28858 0.02354 0.97585 0 7.65649 0.29359 6.77766 0.25988 2.20949 0.15907 1.95607 0.14079 59647.137345 0.000634 0.28027 0.02265 0.98174 0 7.40304 0.27938 6.58524 0.24849 2.07485 0.14830 1.84810 0.13208 59647.139124 0.001146 0.25638 0.01550 0.98232 0 7.81635 0.21318 6.97634 0.19026 2.00398 0.10817 1.78594 0.09638
