/* ** ** 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 57656.765801 0.000602 0.16593 0.02574 0.94231 0 3.81632 0.21946 3.02393 0.17389 0.63326 0.09125 0.50250 0.07240 57656.766952 0.000550 0.22478 0.03548 0.97895 0 2.99786 0.20605 2.38688 0.16406 0.67387 0.09574 0.53628 0.07619 57656.768139 0.000637 0.16398 0.02539 0.98636 0 3.49942 0.20418 2.77891 0.16214 0.57385 0.08229 0.45581 0.06537 57656.769351 0.000576 0.16009 0.02506 0.99497 0 3.88306 0.22483 3.08154 0.17842 0.62165 0.09041 0.49320 0.07173 57656.770239 0.000312 0.15649 0.03760 0.93519 0 3.19420 0.28056 2.53573 0.22273 0.49986 0.11177 0.39670 0.08870 57656.771125 0.000573 0.19463 0.03035 0.97475 0 3.33390 0.20951 2.64486 0.16621 0.64887 0.09262 0.51466 0.07346 57656.772320 0.000622 0.16983 0.02651 0.97209 0 3.49760 0.21025 2.77541 0.16683 0.59400 0.08559 0.47125 0.06790 57656.773535 0.000593 0.16017 0.02444 0.99024 0 3.88599 0.22277 3.08001 0.17657 0.62243 0.08803 0.49343 0.06978 57656.775242 0.001114 0.16932 0.01914 0.96883 0 3.67985 0.15835 2.91099 0.12526 0.62307 0.06512 0.49300 0.05153
