/* ** ** 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 56497.736873 0.001157 0.34823 0.02926 0.95750 0 6.09424 0.25722 2.94709 0.12322 2.12220 0.15421 1.02996 0.07409 56497.739008 0.000978 0.37851 0.03189 0.97337 0 6.49668 0.28663 3.16901 0.13981 2.45904 0.17652 1.20152 0.08623 56497.740336 0.000350 0.38293 0.06002 0.95041 0 5.23250 0.42956 2.57439 0.21134 2.00366 0.26753 0.98578 0.13162 56497.740993 0.000307 0.35035 0.05809 0.97170 0 5.66342 0.47735 2.77272 0.23364 1.98419 0.28329 0.96448 0.13765 56497.741659 0.000359 0.28210 0.04566 0.96774 0 6.08324 0.46352 2.92526 0.22286 1.71607 0.24503 0.82784 0.11815 56497.743137 0.001120 0.35734 0.02977 0.97674 0 6.12363 0.26160 2.93175 0.12521 2.18820 0.15654 1.04904 0.07503 56497.744578 0.000321 0.35565 0.05901 0.95495 0 5.41120 0.45762 2.65034 0.22412 1.92447 0.27470 0.93718 0.13375 56497.745206 0.000307 0.34587 0.05755 0.99057 0 5.62618 0.48119 2.73662 0.23403 1.94591 0.27773 0.94610 0.13503 56497.745840 0.000327 0.28069 0.04520 0.98230 0 6.60273 0.50018 3.18280 0.24102 1.85330 0.26334 0.89868 0.12767 56497.746691 0.000524 0.32088 0.04180 0.95028 0 5.92587 0.37422 2.82395 0.17824 1.90152 0.21664 0.91053 0.10363
