/* ** ** 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 59182.964632 0.000761 0.13480 0.01051 0.98479 0 12.16763 0.32145 11.17458 0.29520 1.64016 0.12038 1.50684 0.11061 59182.966238 0.000845 0.12782 0.00971 0.97945 0 11.77597 0.29830 10.86084 0.27511 1.50518 0.10776 1.38882 0.09943 59182.967953 0.000871 0.12625 0.00954 0.99668 0 11.43598 0.29147 10.53249 0.26844 1.44378 0.10273 1.32978 0.09461 59182.969675 0.000845 0.12400 0.00935 0.98973 0 12.12066 0.30323 11.13609 0.27860 1.50290 0.10693 1.38040 0.09822 59182.971316 0.000796 0.14034 0.01064 0.99273 0 11.37709 0.30336 10.47117 0.27918 1.59670 0.11333 1.46864 0.10423 59182.973194 0.001082 0.12543 0.00860 0.99465 0 11.58234 0.26328 10.53315 0.23941 1.45272 0.09393 1.32231 0.08549
