/* ** ** 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 58258.926307 0.000411 0.17384 0.01348 1.00000 0 17.68069 0.52918 16.10904 0.48211 3.07354 0.21990 2.79809 0.20021 58258.927094 0.000376 0.17872 0.01388 0.99231 0 18.94850 0.57261 17.26650 0.52172 3.38654 0.24234 3.08007 0.22038 58258.927872 0.000402 0.16785 0.01310 1.00000 0 18.65769 0.55069 16.99210 0.50150 3.13161 0.22618 2.84889 0.20574 58258.928700 0.000425 0.15122 0.01170 0.97959 0 19.74057 0.54846 18.18560 0.50525 2.98513 0.21558 2.74997 0.19859 58258.929502 0.000376 0.18765 0.01454 1.00000 0 17.84404 0.55670 16.43832 0.51285 3.34841 0.23757 3.08462 0.21885 58258.930251 0.000373 0.19427 0.01520 1.00000 0 17.21092 0.54562 15.85456 0.50262 3.34352 0.23923 3.08007 0.22038 58258.931296 0.000671 0.17526 0.01064 0.98387 0 17.58485 0.41151 16.20023 0.37911 3.08192 0.17256 2.83925 0.15897 58258.993148 0.001270 0.16979 0.00989 0.98602 0 15.41080 0.34022 9.94587 0.21766 2.61659 0.14104 1.68851 0.09027
