/* ** ** 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 59371.315459 0.000961 0.24891 0.01985 0.98795 0 5.57813 0.20018 4.89004 0.17547 1.38844 0.09888 1.21828 0.08676 59371.316723 0.000304 0.19320 0.02974 1.00000 0 5.76095 0.36336 5.08464 0.32070 1.11301 0.15627 0.98237 0.13793 59371.317476 0.000448 0.18660 0.02408 0.97419 0 5.92184 0.30294 5.22292 0.26719 1.10499 0.13094 0.97467 0.11550 59371.318830 0.000906 0.25270 0.02043 0.99361 0 5.71667 0.21157 5.03380 0.18631 1.44461 0.10381 1.27184 0.09140 59371.320083 0.000347 0.17559 0.02759 0.95000 0 5.58817 0.33685 4.90264 0.29554 0.98123 0.14240 0.86068 0.12491 59371.322010 0.001574 0.22822 0.01507 0.95986 0 5.65735 0.16291 4.94199 0.14230 1.29111 0.07673 1.12922 0.06710
