/* ** ** 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 59854.836597 0.000764 0.26723 0.02165 0.97348 0 6.43096 0.24062 5.75235 0.21520 1.71853 0.12347 1.53875 0.11055 59854.838073 0.000712 0.27521 0.02255 0.98374 0 6.56044 0.24890 5.88192 0.22316 1.80548 0.13111 1.61978 0.11762 59854.839586 0.000802 0.25361 0.02024 0.98195 0 6.46121 0.23414 5.79494 0.20999 1.63865 0.11650 1.47083 0.10457 59854.841146 0.000758 0.23982 0.01923 0.97328 0 7.24523 0.25545 6.44328 0.22717 1.73755 0.12516 1.54741 0.11147 59854.842709 0.000804 0.24149 0.01931 0.98201 0 6.72246 0.23853 6.01049 0.21324 1.62338 0.11631 1.45174 0.10402 59854.844323 0.000810 0.23591 0.01870 0.98571 0 6.93363 0.24055 6.11401 0.21212 1.63573 0.11658 1.44226 0.10279
