/* ** ** 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 57594.168546 0.000460 0.21585 0.03394 0.93082 0 4.51221 0.29250 3.17144 0.20433 0.97395 0.13953 0.67330 0.09578 57594.169558 0.000553 0.16850 0.02632 0.96335 0 4.78784 0.27904 3.17714 0.18510 0.80673 0.11690 0.53312 0.07719 57594.170693 0.000582 0.18409 0.02870 0.97512 0 4.14125 0.25589 2.74504 0.16962 0.76234 0.10911 0.50577 0.07237 57594.171755 0.000480 0.22399 0.03540 0.93976 0 4.32178 0.28985 2.84165 0.19062 0.96802 0.13853 0.63545 0.09093 57594.172750 0.000515 0.19574 0.03082 0.98315 0 4.38565 0.28031 2.88779 0.18453 0.85845 0.12355 0.56350 0.08111 57594.173609 0.000344 0.11712 0.02812 0.98319 0 4.41783 0.34687 2.88154 0.22624 0.51744 0.11741 0.33802 0.07670 57594.174420 0.000466 0.21760 0.03431 0.97516 0 4.44578 0.30229 2.91431 0.19814 0.96739 0.13761 0.63470 0.09029 57594.175389 0.000503 0.19979 0.03149 0.96552 0 4.47185 0.28695 2.93243 0.18815 0.89345 0.12862 0.58697 0.08449 57594.176286 0.000394 0.24228 0.03888 0.99265 0 4.56388 0.32370 3.01504 0.21385 1.10575 0.15919 0.73046 0.10514 57594.177235 0.000556 0.19501 0.03021 0.97917 0 4.18515 0.26470 2.73461 0.17294 0.81613 0.11542 0.53280 0.07535 57594.178459 0.000668 0.19121 0.02737 0.96537 0 4.24557 0.24472 2.78367 0.16044 0.81178 0.10635 0.53204 0.06970
