/* ** ** 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 59144.203659 0.000399 0.27439 0.00992 1.00000 0 57.50032 0.96526 52.41933 0.87993 15.77763 0.50530 14.37869 0.46050 59144.204478 0.000420 0.25967 0.00936 1.00000 0 58.47300 0.95769 52.69351 0.86295 15.18376 0.48726 13.67482 0.43880 59144.205326 0.000428 0.25667 0.00919 1.00000 0 58.37914 0.94504 52.54591 0.85055 14.98408 0.47877 13.49038 0.43103 59144.206153 0.000399 0.27088 0.00983 1.00000 0 58.99322 0.98667 52.93903 0.88539 15.97986 0.51461 14.33135 0.46156 59144.206966 0.000414 0.26157 0.00947 1.00000 0 59.22953 0.97308 52.90902 0.86922 15.49263 0.50004 13.83647 0.44656 59144.207802 0.000422 0.26418 0.00953 1.00000 0 58.01109 0.95663 51.57995 0.85058 15.32554 0.49170 13.62637 0.43719 59144.208642 0.000417 0.27154 0.00978 1.00000 0 56.91167 0.94926 51.06025 0.85161 15.45370 0.49341 13.86305 0.44263 59144.209463 0.000405 0.27074 0.00977 1.00000 0 58.71282 0.97904 52.46343 0.87482 15.89591 0.50896 14.20402 0.45476 59144.210274 0.000405 0.27746 0.01002 1.00000 0 57.58320 0.97240 51.21381 0.86484 15.97714 0.50982 14.20986 0.45343 59144.211078 0.000399 0.28237 0.01029 1.00000 0 56.86639 0.97159 50.77700 0.86754 16.05716 0.51655 14.34372 0.46139 59144.211894 0.000417 0.26698 0.00965 1.00000 0 58.09370 0.96036 51.87851 0.85759 15.51001 0.49847 13.85168 0.44520 59144.212730 0.000420 0.26536 0.00953 1.00000 0 58.04348 0.95937 51.74749 0.85529 15.40219 0.49088 13.73164 0.43764 59144.213694 0.000544 0.27005 0.00860 1.00000 0 56.88837 0.83377 50.83942 0.74508 15.36259 0.43446 13.73238 0.38835
