/* ** ** 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 55582.366339 0.001062 0.08870 0.00671 0.99728 0 13.18646 0.28214 12.11413 0.25920 1.16961 0.08486 1.07516 0.07802 55582.368301 0.000900 0.10364 0.00792 0.98071 0 13.61014 0.31268 12.46032 0.28624 1.41059 0.10276 1.29090 0.09404 55582.370087 0.000885 0.10495 0.00795 0.99346 0 13.55239 0.31419 12.40632 0.28763 1.42227 0.10253 1.30032 0.09375 55582.371881 0.000909 0.10243 0.00775 0.98726 0 13.53701 0.31024 12.43964 0.28510 1.38653 0.09999 1.27516 0.09194 55582.373084 0.000295 0.08350 0.01231 1.00000 0 12.69519 0.52799 11.76138 0.48916 1.06000 0.14991 0.98203 0.13888 55582.374881 0.001502 0.10474 0.00626 0.98073 0 13.29311 0.23859 12.21112 0.21917 1.39231 0.07939 1.27983 0.07298
