/* ** ** 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 59368.172939 0.000561 0.13517 0.01042 0.98969 0 16.56923 0.43593 15.23713 0.40088 2.23969 0.16227 2.05908 0.14915 59368.174073 0.000573 0.12711 0.00986 0.99495 0 17.13056 0.44337 15.63238 0.40457 2.17738 0.15917 1.98735 0.14531 59368.175245 0.000599 0.12645 0.00977 0.98068 0 16.66322 0.42221 15.33564 0.38853 2.10700 0.15372 1.93848 0.14136 59368.176403 0.000558 0.13643 0.01034 1.00000 0 16.44568 0.43645 15.22294 0.40400 2.24375 0.15932 2.07688 0.14747 59368.177580 0.000619 0.12603 0.00964 0.98598 0 16.16545 0.41138 14.87813 0.37860 2.03727 0.14700 1.87285 0.13511 59368.178807 0.000608 0.12904 0.00995 0.99048 0 15.94277 0.41466 14.67183 0.38160 2.05727 0.14941 1.89106 0.13734 59368.180043 0.000628 0.12603 0.00959 0.99078 0 15.88200 0.40676 14.67175 0.37576 2.00168 0.14344 1.84653 0.13232 59368.181640 0.000969 0.13499 0.00796 0.98806 0 16.39504 0.33273 15.07578 0.30596 2.21323 0.12254 2.03671 0.11275
