/* ** ** 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 59334.184152 0.000703 0.11998 0.00928 0.98354 0 17.07808 0.42772 13.58118 0.33936 2.04901 0.14998 1.63819 0.11977 59334.185399 0.000544 0.16268 0.01252 0.98936 0 16.92937 0.49123 13.24711 0.38435 2.75401 0.19635 2.15601 0.15371 59334.186557 0.000613 0.13760 0.01052 0.99057 0 17.44876 0.46450 13.73700 0.36569 2.40092 0.17205 1.89053 0.13547 59334.187711 0.000541 0.16636 0.01284 0.98396 0 16.57021 0.48293 13.02885 0.37970 2.75667 0.19703 2.16856 0.15500 59334.188921 0.000668 0.13089 0.01016 0.98268 0 16.78415 0.43719 13.17860 0.34327 2.19691 0.16058 1.72480 0.12610 59334.190194 0.000605 0.14106 0.01094 0.99522 0 17.07966 0.46662 13.40751 0.36629 2.40928 0.17496 1.89114 0.13734 59334.191580 0.000781 0.14686 0.01023 0.98574 0 16.33553 0.40353 12.69328 0.31352 2.39897 0.15620 1.86381 0.12133
