/* ** ** 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 58249.961824 0.000761 0.14076 0.01075 0.99240 0 12.07414 0.32331 10.91416 0.29224 1.69958 0.12154 1.53663 0.10989 58249.963479 0.000894 0.12235 0.00924 0.97735 0 12.14466 0.30097 10.83343 0.26847 1.48594 0.10604 1.32603 0.09462 58249.964677 0.000304 0.09052 0.01423 0.98095 0 11.59100 0.50772 10.37278 0.45436 1.04919 0.15844 0.93741 0.14155 58249.965750 0.000770 0.13713 0.01064 0.98120 0 12.22507 0.32418 10.98263 0.29120 1.67639 0.12226 1.50514 0.10975 58249.967235 0.000715 0.15519 0.01207 0.99190 0 11.56829 0.32894 10.34791 0.29422 1.79528 0.13002 1.60672 0.11635 58249.968820 0.000865 0.12305 0.00939 0.98997 0 12.11796 0.30420 10.86693 0.27277 1.49107 0.10745 1.33463 0.09618 58249.970950 0.001264 0.12364 0.00787 0.98169 0 12.09876 0.25293 10.75992 0.22494 1.49593 0.08990 1.33132 0.07999
