/* ** ** 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 59016.075273 0.000310 0.35561 0.09495 0.94393 0 2.90358 0.39194 1.18108 0.15553 1.03253 0.23789 0.39670 0.08870 59016.075932 0.000350 0.27609 0.07148 0.97521 0 2.71500 0.33283 1.21112 0.14831 0.74959 0.17094 0.33512 0.07605 59016.076786 0.000503 0.25509 0.06426 0.97126 0 2.51269 0.29051 0.93134 0.10759 0.64097 0.14346 0.23708 0.05301 59016.077882 0.000593 0.20296 0.05021 0.97561 0 2.67557 0.28305 0.97941 0.10361 0.54303 0.12145 0.20033 0.04480 59016.079164 0.000689 0.16734 0.04066 0.96218 0 2.88616 0.27424 1.04440 0.09924 0.48298 0.10800 0.17496 0.03912 59016.080536 0.000683 0.15458 0.03847 0.98305 0 2.97064 0.27899 1.09081 0.10239 0.45921 0.10585 0.16819 0.03875 59016.081803 0.000584 0.17673 0.04361 0.97030 0 3.12414 0.30230 1.14507 0.11074 0.55212 0.12532 0.20175 0.04579 59016.082990 0.000602 0.25366 0.06397 0.96154 0 2.15233 0.25064 0.78747 0.09167 0.54595 0.12214 0.20033 0.04480 59016.084156 0.000564 0.24937 0.05847 0.94872 0 2.79770 0.30935 1.02425 0.11315 0.69765 0.14426 0.25706 0.05313
