/* ** ** 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 56401.404905 0.000425 0.21594 0.03494 0.95918 0 3.88827 0.25808 3.18258 0.21121 0.83963 0.12389 0.68408 0.10096 56401.405758 0.000428 0.21147 0.03314 0.98649 0 3.90715 0.25682 3.22576 0.21203 0.82627 0.11756 0.68244 0.09709 56401.406594 0.000408 0.24999 0.04034 0.95035 0 3.54491 0.25191 2.92302 0.20770 0.88617 0.12840 0.73168 0.10601 56401.407353 0.000350 0.26267 0.04233 0.94215 0 3.97434 0.28743 3.29105 0.23800 1.04395 0.15033 0.86470 0.12452 56401.408044 0.000341 0.26483 0.04222 1.00000 0 3.84234 0.28262 3.20443 0.23570 1.01756 0.14390 0.84887 0.12005 56401.408805 0.000420 0.19285 0.03044 0.95862 0 4.41558 0.27673 3.66240 0.22952 0.85156 0.12337 0.70536 0.10220 56401.409604 0.000379 0.23430 0.03684 0.96947 0 4.03695 0.27764 3.36642 0.23152 0.94584 0.13376 0.78871 0.11154 56401.410426 0.000443 0.20756 0.03303 0.98039 0 3.77938 0.24892 3.14877 0.20739 0.78443 0.11365 0.65364 0.09470 56401.411198 0.000330 0.25780 0.04121 0.98246 0 4.16504 0.30342 3.43656 0.25036 1.07377 0.15278 0.88961 0.12657 56401.411945 0.000417 0.22087 0.03538 0.99306 0 3.73649 0.25524 3.10529 0.21213 0.82526 0.11956 0.68563 0.09934 56401.412732 0.000370 0.24359 0.03896 0.94531 0 4.04082 0.28139 3.34769 0.23311 0.98430 0.14174 0.81468 0.11732 56401.413467 0.000365 0.24126 0.03849 0.98413 0 3.97454 0.28005 3.31302 0.23344 0.95888 0.13725 0.79924 0.11440 56401.414187 0.000350 0.24061 0.03853 0.98347 0 4.13200 0.28942 3.44151 0.24105 0.99422 0.14317 0.82837 0.11929 56401.414942 0.000405 0.23484 0.03656 0.95714 0 3.90144 0.26553 3.24667 0.22096 0.91620 0.12829 0.76246 0.10677 56401.415703 0.000356 0.23245 0.03693 0.97561 0 4.27353 0.29473 3.55396 0.24511 0.99338 0.14219 0.82588 0.11821 56401.416690 0.000631 0.31975 0.03859 0.95872 0 3.31192 0.19678 2.75635 0.16377 1.05900 0.11125 0.88129 0.09258
