/* ** ** 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 55204.289969 0.000399 0.26146 0.00943 1.00000 0 59.15717 0.96699 55.20122 0.90231 15.46730 0.49704 14.43680 0.46391 55204.290779 0.000411 0.24720 0.00888 1.00000 0 61.36258 0.98191 56.43621 0.90310 15.16873 0.48769 13.94937 0.44850 55204.291592 0.000402 0.25073 0.00901 1.00000 0 62.25566 1.00165 56.98479 0.91683 15.60936 0.50137 14.27926 0.45864 55204.292431 0.000437 0.23763 0.00852 0.95691 0 63.00954 0.98918 57.67571 0.90542 14.97271 0.48264 13.70488 0.44176 55204.293256 0.000388 0.26047 0.00933 1.00000 0 62.46460 1.02159 57.18816 0.93523 16.26992 0.51862 14.89507 0.47477 55204.294402 0.000758 0.26313 0.00684 0.99618 0 61.18932 0.72315 56.03555 0.66223 16.10087 0.37245 14.74454 0.34107 55204.336164 0.000472 0.22306 0.00796 1.00000 0 58.98280 0.89812 54.70901 0.83305 13.15642 0.42450 12.20020 0.39363 55204.337081 0.000446 0.23306 0.00835 1.00000 0 59.61316 0.93246 55.19835 0.86339 13.89338 0.44761 12.86069 0.41431 55204.337996 0.000469 0.22168 0.00793 1.00000 0 59.86764 0.90731 55.22121 0.83679 13.27143 0.42973 12.23245 0.39610 55204.339014 0.000550 0.23932 0.00779 0.99474 0 58.64497 0.82724 54.33910 0.76651 14.03474 0.41195 13.00410 0.38169
