/* ** ** 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 56041.166319 0.000434 0.09456 0.01902 0.94000 0 5.09736 0.29132 4.14709 0.23699 0.48203 0.09294 0.39075 0.07535 56041.167167 0.000414 0.09280 0.01872 0.98601 0 5.09481 0.30236 4.20291 0.24939 0.47279 0.09117 0.39075 0.07535 56041.168200 0.000619 0.10602 0.01594 0.97664 0 5.38799 0.24960 4.47682 0.20739 0.57125 0.08172 0.47449 0.06786 56041.169120 0.000301 0.08405 0.01984 1.00000 0 5.46322 0.35930 4.52705 0.29772 0.45918 0.10413 0.38046 0.08628 56041.169762 0.000341 0.08391 0.01952 0.94915 0 5.11190 0.32779 4.26370 0.27340 0.42892 0.09591 0.35774 0.07999 56041.170416 0.000312 0.09361 0.02138 1.00000 0 4.98964 0.33632 4.16126 0.28049 0.46708 0.10193 0.38954 0.08500 56041.171307 0.000579 0.11937 0.01826 0.97500 0 5.07854 0.25181 4.21998 0.20924 0.60624 0.08770 0.50344 0.07282 56041.172462 0.000576 0.11423 0.01705 0.97487 0 5.43732 0.25987 4.52044 0.21605 0.62111 0.08784 0.51632 0.07302 56041.173347 0.000310 0.08999 0.02079 0.99065 0 5.22789 0.34922 4.35835 0.29114 0.47045 0.10405 0.39218 0.08674 56041.174655 0.000998 0.10118 0.01251 0.96812 0 5.15648 0.19213 4.29851 0.16016 0.52171 0.06153 0.43487 0.05129
