/* ** ** 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 59394.023573 0.000943 0.31837 0.02606 0.96933 0 4.60267 0.18549 3.95170 0.15926 1.46536 0.10441 1.25952 0.08974 59394.024826 0.000310 0.22356 0.03514 0.98131 0 4.90506 0.32788 4.24233 0.28358 1.09657 0.15602 0.94890 0.13501 59394.026175 0.001039 0.28074 0.02278 0.97214 0 4.67219 0.17761 4.04016 0.15358 1.31169 0.09402 1.13433 0.08131 59394.028186 0.000972 0.29583 0.02404 0.97619 0 4.74776 0.18642 4.10662 0.16125 1.40455 0.09992 1.21506 0.08644 59394.029473 0.000315 0.19313 0.03018 0.98165 0 5.54522 0.34777 4.79593 0.30077 1.07093 0.15329 0.92620 0.13258 59394.030755 0.000966 0.29052 0.02337 0.97305 0 4.91937 0.18850 4.25417 0.16301 1.42919 0.10111 1.23571 0.08742 59394.032135 0.000414 0.23626 0.03214 0.95804 0 4.82498 0.28708 4.17728 0.24854 1.13995 0.13947 0.98659 0.12071 59394.033631 0.001082 0.28511 0.02224 0.97594 0 4.76354 0.17512 4.11711 0.15135 1.35811 0.09345 1.17388 0.08077
