/* ** ** 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 59133.240728 0.000527 0.24759 0.00891 1.00000 0 47.61255 0.76057 43.79467 0.69956 11.78848 0.38032 10.84427 0.34986 59133.241741 0.000486 0.27053 0.00978 1.00000 0 47.91275 0.80090 43.85661 0.73303 12.96177 0.41557 11.86273 0.38026 59133.242745 0.000518 0.25621 0.00925 1.00000 0 47.26292 0.76977 43.08851 0.70172 12.10907 0.39010 11.04630 0.35578 59133.243757 0.000495 0.26337 0.00948 1.00000 0 47.94079 0.78971 44.10055 0.72641 12.62623 0.40436 11.61068 0.37182 59133.244750 0.000498 0.25937 0.00931 1.00000 0 48.52486 0.79059 44.68250 0.72797 12.58578 0.40250 11.59195 0.37069 59133.246223 0.000975 0.26797 0.00696 0.99993 0 46.17104 0.55169 42.59135 0.50889 12.37254 0.28529 11.41483 0.26319
