/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 57412.912294 0.000436 0.22958 0.03651 0.96667 1 13.77666 0.92863 2.95542 0.19921 3.16279 0.45557 0.67807 0.09767 57412.913297 0.000566 0.16458 0.02540 0.97436 1 14.77780 0.85838 3.16287 0.18371 2.43214 0.34776 0.52101 0.07450 57412.914299 0.000436 0.21000 0.03256 1.00000 1 15.09171 0.98582 3.25959 0.21292 3.16930 0.44572 0.68437 0.09625 57412.915301 0.000508 0.20225 0.03172 1.00000 1 12.95861 0.83442 2.79214 0.17978 2.62090 0.37476 0.56567 0.08088 57412.916362 0.000552 0.18936 0.02924 0.97368 1 13.48920 0.82858 2.91140 0.17883 2.55438 0.36184 0.55127 0.07808 57412.917843 0.000901 0.21241 0.02398 0.98404 1 13.87024 0.65474 2.98225 0.14077 2.94611 0.30209 0.63370 0.06498
