/* ** ** 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 59786.926280 0.000518 0.27376 0.02214 0.99441 0 9.09879 0.34283 8.19392 0.30873 2.49090 0.17822 2.24352 0.16052 59786.927333 0.000535 0.28935 0.02368 0.97297 0 8.31721 0.32123 7.57015 0.29238 2.40658 0.17366 2.19041 0.15806 59786.928404 0.000535 0.27464 0.02214 0.99459 0 8.71271 0.32850 7.90132 0.29790 2.39284 0.17049 2.17105 0.15468 59786.929500 0.000561 0.25579 0.02082 0.97423 0 8.92768 0.32366 8.07872 0.29290 2.28360 0.16646 2.06919 0.15085 59786.930629 0.000567 0.27201 0.02175 0.98980 0 8.36205 0.31110 7.61028 0.28313 2.27460 0.16098 2.07013 0.14651 59786.932267 0.001071 0.26931 0.01566 0.98570 0 8.60536 0.23098 7.77652 0.20872 2.31753 0.11957 2.09434 0.10806
