/* ** ** 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 58367.874306 0.000350 0.26824 0.06935 0.95868 0 1.55126 0.18626 1.26281 0.15164 0.41611 0.09527 0.33801 0.07741 58367.875208 0.000553 0.16749 0.04054 0.96335 0 1.58040 0.14638 1.29869 0.12029 0.26470 0.05919 0.21775 0.04869 58367.876244 0.000483 0.17335 0.04198 0.95210 0 1.77867 0.16538 1.45307 0.13508 0.30832 0.06895 0.25199 0.05635 58367.877133 0.000405 0.18817 0.04655 0.98571 0 1.85355 0.18530 1.52636 0.15259 0.34878 0.07892 0.28723 0.06500 58367.878018 0.000480 0.17752 0.04455 0.94578 0 1.69133 0.16261 1.39113 0.13375 0.30025 0.06960 0.24701 0.05726 58367.879118 0.000619 0.16423 0.03966 0.96729 0 1.43448 0.13085 1.17796 0.10745 0.23558 0.05268 0.19356 0.04328 58367.880113 0.000376 0.22663 0.05635 0.98462 0 1.68830 0.18348 1.37718 0.14968 0.38262 0.08556 0.31302 0.06999 58367.881094 0.000605 0.12104 0.02967 0.97129 0 1.92650 0.15364 1.57974 0.12598 0.23319 0.05405 0.19104 0.04429 58367.882228 0.000530 0.14712 0.03619 0.97268 0 1.83436 0.16454 1.49497 0.13408 0.26987 0.06181 0.22028 0.05045 58367.883180 0.000417 0.22131 0.05473 0.97222 0 1.57117 0.16600 1.29298 0.13661 0.34772 0.07775 0.28619 0.06399 58367.883993 0.000396 0.23206 0.05863 0.98540 0 1.55314 0.17452 1.26330 0.14196 0.36042 0.08155 0.29362 0.06644 58367.884899 0.000509 0.19112 0.04274 0.97727 0 1.77861 0.16246 1.46251 0.13359 0.33992 0.06939 0.27954 0.05706
