/* ** ** 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 59374.218941 0.000735 0.11634 0.00884 1.00000 0 14.64278 0.35816 13.42244 0.32829 1.70356 0.12252 1.56404 0.11249 59374.220411 0.000735 0.12480 0.00938 0.99213 0 13.90991 0.35090 12.81041 0.32316 1.73591 0.12293 1.59870 0.11321 59374.221872 0.000726 0.12373 0.00949 0.97610 0 14.19530 0.35830 13.04190 0.32916 1.75638 0.12715 1.61414 0.11686 59374.223385 0.000787 0.11133 0.00851 0.98529 0 14.31782 0.34367 13.18741 0.31653 1.59400 0.11570 1.46814 0.10657 59374.224988 0.000816 0.11093 0.00843 0.98582 0 13.91516 0.33405 12.81725 0.30770 1.54360 0.11131 1.42181 0.10253 59374.227124 0.001319 0.10639 0.00638 0.98465 0 14.51099 0.26756 13.36616 0.24645 1.54379 0.08808 1.42199 0.08113
