/* ** ** 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 59701.500093 0.000642 0.12280 0.00937 0.99550 0 15.72636 0.39703 14.61356 0.36893 1.93117 0.13909 1.79452 0.12925 59701.501471 0.000735 0.10777 0.00824 0.99606 0 15.51317 0.37045 14.41561 0.34424 1.67191 0.12137 1.55362 0.11279 59701.502938 0.000732 0.10973 0.00830 0.99209 0 15.52174 0.36915 14.38678 0.34216 1.70320 0.12235 1.57811 0.11336 59701.504381 0.000712 0.11457 0.00872 0.98374 0 15.31576 0.37033 14.23224 0.34413 1.75466 0.12671 1.63052 0.11774 59701.505776 0.000683 0.12015 0.00932 1.00000 0 14.80198 0.37320 13.75460 0.34679 1.77850 0.13049 1.65265 0.12125 59701.507185 0.000726 0.11157 0.00845 0.98406 0 15.49673 0.36990 14.36786 0.34296 1.72904 0.12420 1.60367 0.11520 59701.508600 0.000689 0.12481 0.00965 0.97479 0 14.55734 0.37012 13.52366 0.34384 1.81692 0.13260 1.68770 0.12317 59701.510053 0.000764 0.10960 0.00838 0.98485 0 14.84362 0.35424 13.79336 0.32917 1.62690 0.11811 1.51179 0.10975 59701.511638 0.000822 0.11814 0.00822 0.97887 0 15.65188 0.35020 14.54442 0.32543 1.84914 0.12174 1.71831 0.11313
