/* ** ** 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 58294.138730 0.000466 0.14033 0.03355 0.98137 0 2.16875 0.18365 1.80460 0.15281 0.30435 0.06806 0.25359 0.05670 58294.139803 0.000608 0.11171 0.02677 0.96667 0 2.09461 0.16087 1.74273 0.13384 0.23398 0.05311 0.19478 0.04421 58294.140703 0.000292 0.22408 0.05573 1.00000 0 2.13295 0.23220 1.76831 0.19247 0.47796 0.10688 0.39670 0.08870 58294.141554 0.000558 0.13490 0.03225 0.97927 0 1.89310 0.16024 1.56470 0.13246 0.25537 0.05711 0.21199 0.04740 58294.142569 0.000457 0.13091 0.03170 0.97468 0 2.36865 0.19978 1.96398 0.16566 0.31007 0.07037 0.25676 0.05828 58294.143657 0.000625 0.11309 0.02757 0.98148 0 1.97456 0.15615 1.63029 0.12891 0.22331 0.05149 0.18403 0.04241 58294.144928 0.000645 0.11470 0.02716 0.96413 0 1.94912 0.15175 1.62627 0.12662 0.22356 0.04999 0.18636 0.04167 58294.146181 0.000608 0.10575 0.02528 0.96667 0 2.20522 0.16550 1.84177 0.13823 0.23321 0.05293 0.19478 0.04421 58294.147526 0.000738 0.10340 0.02436 0.96863 0 1.87582 0.13924 1.56821 0.11640 0.19396 0.04337 0.16221 0.03627 58294.148626 0.000362 0.20315 0.05012 0.99200 0 1.90714 0.19877 1.59057 0.16578 0.38743 0.08663 0.32312 0.07225 58294.149606 0.000619 0.11556 0.02735 0.96262 0 2.01341 0.15603 1.68354 0.13047 0.23267 0.05203 0.19450 0.04349 58294.150848 0.000622 0.11065 0.02617 0.97674 0 2.06957 0.15942 1.72421 0.13282 0.22899 0.05121 0.19079 0.04266 58294.152124 0.000654 0.14378 0.02949 0.98673 0 2.07145 0.15491 1.73237 0.12956 0.29782 0.05689 0.24918 0.04760
