/* ** ** 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 59442.016361 0.000443 0.23319 0.03748 0.98039 0 3.25356 0.22586 2.79704 0.19416 0.75871 0.10998 0.65336 0.09471 59442.017229 0.000425 0.26449 0.04230 0.94558 0 3.16304 0.23074 2.71801 0.19827 0.83658 0.11905 0.71673 0.10199 59442.018097 0.000443 0.24771 0.03935 0.95425 0 3.18623 0.22492 2.75305 0.19432 0.78925 0.11230 0.68237 0.09710 59442.018922 0.000382 0.28513 0.04617 0.95455 0 3.22927 0.24402 2.76181 0.20869 0.92076 0.13185 0.78639 0.11259 59442.019741 0.000437 0.24846 0.04017 0.97351 0 3.14149 0.22503 2.68838 0.19255 0.78055 0.11314 0.66669 0.09665 59442.020696 0.000518 0.20555 0.03231 0.97207 0 3.23809 0.21013 2.77286 0.17992 0.66560 0.09528 0.56946 0.08153 59442.022064 0.000851 0.21086 0.02470 0.98089 0 3.44261 0.17068 2.94996 0.14625 0.72590 0.07705 0.62147 0.06596
