/* ** ** 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 58316.935329 0.000856 0.08351 0.01945 0.97297 0 1.99930 0.13025 1.65982 0.10813 0.16696 0.03733 0.13912 0.03111 58316.936547 0.000362 0.21318 0.05362 0.97600 0 1.82477 0.19764 1.51771 0.16435 0.38901 0.08830 0.32406 0.07356 58316.937569 0.000660 0.13741 0.03328 0.96930 0 1.55597 0.13119 1.30186 0.10977 0.21381 0.04854 0.17890 0.04061 58316.938836 0.000608 0.13101 0.03116 0.98095 0 1.77431 0.14399 1.48464 0.12049 0.23245 0.05198 0.19450 0.04349 58316.939806 0.000362 0.20710 0.05188 0.98400 0 1.85404 0.19650 1.55259 0.16455 0.38397 0.08717 0.32143 0.07297 58316.940836 0.000668 0.14921 0.03576 0.96104 0 1.44937 0.12512 1.20920 0.10438 0.21625 0.04836 0.18048 0.04036 58316.942051 0.000547 0.15946 0.03899 0.98413 0 1.59398 0.14478 1.33053 0.12085 0.25417 0.05770 0.21256 0.04825 58316.943081 0.000483 0.17229 0.04240 0.99401 0 1.65859 0.15770 1.38428 0.13162 0.28575 0.06487 0.23817 0.05407 58316.944684 0.001120 0.12942 0.02314 0.98708 0 1.73143 0.10584 1.44569 0.08837 0.22408 0.03766 0.18741 0.03150
