/* ** ** 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 58630.954565 0.000208 0.25164 0.01989 1.00000 0 25.24933 0.89530 22.28023 0.78998 6.35373 0.44897 5.60240 0.39587 58630.954944 0.000171 0.30823 0.02520 1.00000 0 24.95390 0.99445 22.07668 0.87978 7.69156 0.54910 6.80468 0.48578 58630.955295 0.000179 0.26578 0.02182 1.00000 0 27.17402 1.01455 23.83662 0.88998 7.22238 0.52817 6.33827 0.46352 58630.955650 0.000177 0.30624 0.02519 1.00000 0 23.95419 0.95610 21.17207 0.84502 7.33583 0.52772 6.48305 0.46640 58630.956035 0.000208 0.24710 0.01969 1.00000 0 25.71887 0.91277 22.70000 0.80562 6.35511 0.45335 5.61365 0.40042 58630.956443 0.000200 0.27006 0.02167 1.00000 0 24.55759 0.91336 21.60976 0.80370 6.63207 0.47145 5.83733 0.41495 58630.956863 0.000220 0.24117 0.01892 1.00000 0 25.05124 0.87178 22.22644 0.77348 6.04152 0.42478 5.36025 0.37688 58630.957285 0.000203 0.26325 0.02131 0.98571 0 24.81281 0.91432 21.84112 0.80477 6.53200 0.47078 5.74159 0.41377 58630.957702 0.000214 0.25218 0.01991 1.00000 0 24.43259 0.87619 21.68571 0.77768 6.16130 0.43351 5.46855 0.38477 58630.958127 0.000211 0.27491 0.02191 0.99213 0 23.48141 0.87030 20.83776 0.77232 6.45528 0.45546 5.72867 0.40419
