/* ** ** 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 56077.273125 0.000564 0.28740 0.02358 0.99487 0 7.77617 0.29932 7.05226 0.27144 2.23489 0.16189 2.02632 0.14678 56077.274221 0.000532 0.34927 0.02904 0.98370 0 6.94024 0.29240 6.25750 0.26362 2.42403 0.17379 2.18976 0.15698 56077.275272 0.000518 0.34919 0.02913 0.98324 0 7.07875 0.29912 6.43151 0.27177 2.47183 0.17782 2.24583 0.16156 56077.276290 0.000501 0.36417 0.03006 0.98266 0 7.30853 0.31192 6.52774 0.27858 2.66154 0.18808 2.37951 0.16814 56077.277329 0.000538 0.35900 0.02986 0.97849 0 6.74365 0.28725 6.09069 0.25946 2.42100 0.17295 2.18366 0.15601 56077.278292 0.000425 0.41871 0.03609 0.97959 0 7.19999 0.33348 6.49777 0.30094 3.01468 0.21917 2.72240 0.19789 56077.279184 0.000466 0.39624 0.03354 0.99379 0 6.91164 0.31124 6.25649 0.28174 2.73870 0.19633 2.47716 0.17759 56077.280139 0.000489 0.37327 0.03139 1.00000 0 6.94392 0.30512 6.28509 0.27613 2.59198 0.18581 2.34524 0.16813 56077.281125 0.000498 0.34702 0.02887 0.99419 0 7.35112 0.31014 6.67894 0.28178 2.55102 0.18288 2.31781 0.16616 56077.282471 0.000848 0.34258 0.02255 0.98976 0 7.01491 0.23277 6.35942 0.21102 2.40315 0.13659 2.17759 0.12377
