/* ** ** 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 56517.097774 0.000307 0.27064 0.04406 0.98113 0 4.13739 0.30747 3.48578 0.25904 1.11973 0.16217 0.94309 0.13658 56517.098399 0.000318 0.28181 0.04592 0.97273 0 3.80804 0.29057 3.27007 0.24952 1.07316 0.15449 0.92152 0.13266 56517.099068 0.000350 0.24915 0.04032 0.98347 0 3.88284 0.27876 3.33981 0.23978 0.96740 0.14030 0.83228 0.12070 56517.099771 0.000353 0.22000 0.03503 0.99180 0 4.31251 0.29349 3.70410 0.25209 0.94876 0.13658 0.81490 0.11731 56517.100451 0.000327 0.25751 0.04080 0.97345 0 4.11692 0.29401 3.53622 0.25254 1.06016 0.14993 0.91061 0.12878 56517.101099 0.000321 0.29038 0.04702 0.95495 0 3.74916 0.28403 3.22039 0.24397 1.08869 0.15579 0.93513 0.13382 56517.101842 0.000422 0.22536 0.03555 0.93836 0 3.73812 0.24816 3.21063 0.21314 0.84241 0.12055 0.72353 0.10354 56517.102635 0.000370 0.23394 0.03731 0.98438 0 3.96780 0.27742 3.38998 0.23700 0.92822 0.13306 0.79432 0.11385 56517.103318 0.000312 0.23409 0.03674 0.96296 0 4.78776 0.32571 4.11437 0.27990 1.12075 0.15850 0.96314 0.13621 56517.103926 0.000295 0.26705 0.04312 1.00000 0 4.23636 0.31686 3.63921 0.27220 1.13130 0.16189 0.97180 0.13907 56517.104559 0.000339 0.25913 0.04133 0.98291 0 3.90611 0.28175 3.33692 0.24067 1.01219 0.14399 0.86648 0.12326 56517.105242 0.000344 0.28749 0.04623 0.99160 0 3.45221 0.26421 2.94826 0.22562 0.99246 0.14036 0.84887 0.12005 56517.105899 0.000312 0.28383 0.04607 0.99074 0 3.83695 0.29386 3.25898 0.24959 1.08903 0.15586 0.92639 0.13257 56517.106507 0.000295 0.23069 0.03682 0.99020 0 4.92821 0.33994 4.23273 0.29197 1.13689 0.16366 0.97626 0.14054 56517.107117 0.000315 0.33378 0.05361 0.96330 0 3.44252 0.27431 2.95749 0.23566 1.14906 0.16025 0.98716 0.13767 56517.107748 0.000315 0.24123 0.03857 0.95413 0 4.57471 0.31823 3.93030 0.27340 1.10357 0.15887 0.94810 0.13649 56517.108547 0.000483 0.23671 0.03228 0.97605 0 4.03344 0.24012 3.46513 0.20629 0.95475 0.11716 0.82026 0.10065
