/* ** ** 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 56078.208175 0.000550 0.36195 0.03028 0.99474 0 6.34997 0.27367 5.79366 0.24969 2.29837 0.16478 2.09699 0.15034 56078.209251 0.000527 0.36055 0.02993 0.98352 0 6.89618 0.29494 6.22833 0.26638 2.48639 0.17692 2.24772 0.15992 56078.210389 0.000611 0.33158 0.02718 0.97630 0 6.46853 0.26482 5.86975 0.24030 2.14484 0.15235 1.94419 0.13808 56078.211595 0.000596 0.32173 0.02641 0.98544 0 6.71152 0.27101 6.07440 0.24527 2.15927 0.15431 1.95771 0.13987 56078.212715 0.000518 0.36289 0.03069 0.98883 0 6.81878 0.29755 6.12774 0.26735 2.47445 0.17929 2.22079 0.16088 56078.213826 0.000593 0.34852 0.02807 0.97790 0 6.65903 0.27271 6.01959 0.24651 2.32082 0.16097 2.10235 0.14580
