/* ** ** 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 58118.142919 0.000428 0.21231 0.01707 0.99324 0 29.45709 0.99602 12.60574 0.42259 6.25407 0.45617 2.67607 0.19432 58118.143759 0.000411 0.16364 0.01347 0.97183 0 33.23999 0.98856 16.89595 0.50231 5.43934 0.41741 2.76086 0.21174 58118.144522 0.000353 0.20348 0.01628 0.99180 0 31.78695 1.04585 15.98152 0.52582 6.46816 0.47164 3.25259 0.23713 58118.145208 0.000333 0.20354 0.01619 1.00000 0 33.45249 1.10126 16.88935 0.55599 6.80886 0.49311 3.43813 0.24900 58118.145891 0.000350 0.18437 0.01466 0.99174 0 36.25391 1.12936 17.72342 0.55190 6.68404 0.48887 3.26301 0.23852 58118.146551 0.000310 0.20433 0.01602 1.00000 0 36.88009 1.21161 18.23961 0.59914 7.53565 0.53647 3.72752 0.26533 58118.147390 0.000530 0.19456 0.01230 0.99037 0 36.32045 0.91746 17.83479 0.45047 7.06642 0.40968 3.46984 0.20118
