/* ** ** 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 56527.828577 0.000547 0.34072 0.02863 0.98413 0 6.90249 0.29163 6.20451 0.26211 2.35180 0.17080 2.11509 0.15360 56527.829631 0.000506 0.38744 0.03289 0.97714 0 6.68479 0.29945 5.95455 0.26673 2.58992 0.18677 2.30697 0.16634 56527.830658 0.000521 0.33761 0.02786 0.97778 0 7.56149 0.31281 6.68449 0.27653 2.55287 0.18228 2.25897 0.16129 56527.831697 0.000512 0.36313 0.03029 0.99435 0 7.00365 0.30208 6.22256 0.26837 2.54321 0.18161 2.25897 0.16129 56527.832732 0.000524 0.35344 0.02983 0.98343 0 7.01436 0.29958 6.21932 0.26564 2.47915 0.18051 2.19890 0.16011 56527.833777 0.000521 0.36575 0.03105 0.98889 0 6.81331 0.29991 6.02849 0.26535 2.49196 0.18088 2.20468 0.16000 56527.834865 0.000567 0.33266 0.02779 0.98895 0 6.91185 0.28653 6.15726 0.25521 2.29933 0.16676 2.04999 0.14866 56527.896441 0.000564 0.37001 0.03113 0.97436 0 6.37712 0.27615 5.60441 0.24268 2.35961 0.17021 2.07568 0.14972 56527.897793 0.000787 0.37111 0.02592 0.97426 0 6.66771 0.24047 5.82108 0.20992 2.47448 0.14798 2.16069 0.12922
