/* ** ** 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 56093.987925 0.000469 0.29277 0.04777 0.93210 0 7.13163 0.53224 2.35681 0.17411 2.08794 0.30297 0.65280 0.09401 56093.988834 0.000440 0.36363 0.06145 0.93421 0 6.35505 0.55215 1.89319 0.16448 2.31089 0.33493 0.69043 0.10004 56093.989731 0.000457 0.34582 0.05692 0.95570 0 6.35142 0.53466 1.92454 0.16199 2.19645 0.31065 0.66336 0.09381 56093.990665 0.000477 0.30546 0.05046 0.95152 0 6.80777 0.54011 2.03861 0.16173 2.07951 0.30132 0.62447 0.09048 56093.991583 0.000440 0.30592 0.05067 0.96053 0 7.39292 0.60500 2.19726 0.17982 2.26163 0.32566 0.67516 0.09723 56093.992422 0.000399 0.36410 0.06106 0.95652 0 6.90973 0.59362 2.04874 0.17601 2.51580 0.36231 0.74676 0.10754 56093.993148 0.000327 0.36833 0.06250 0.96460 0 8.32932 0.74733 2.45270 0.21996 3.06797 0.44182 0.90434 0.13023 56093.993811 0.000336 0.37663 0.06418 0.96552 0 7.85987 0.70496 2.32012 0.20807 2.96024 0.42894 0.87537 0.12684 56093.994543 0.000396 0.33400 0.05557 0.95620 0 7.57046 0.63074 2.25334 0.18773 2.52850 0.36414 0.75246 0.10836 56093.995338 0.000399 0.39092 0.06601 0.95652 0 6.47204 0.57968 1.92219 0.17216 2.53005 0.36213 0.75079 0.10747 56093.996227 0.000489 0.26876 0.04386 0.95858 0 7.56118 0.56764 2.25322 0.16914 2.03217 0.29443 0.60519 0.08769 56093.997017 0.000301 0.49970 0.08803 0.97115 0 6.58819 0.67643 1.96577 0.20184 3.29214 0.47127 0.98123 0.14045 56093.997963 0.000645 0.30629 0.04216 0.93722 0 7.36254 0.48902 2.17533 0.14448 2.25508 0.27188 0.66589 0.08028
