/* ** ** 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 56358.318723 0.000489 0.15460 0.01242 0.98225 0 23.82837 0.68934 15.71631 0.43756 3.68397 0.27613 2.38058 0.17174 56358.319600 0.000388 0.17148 0.01356 0.98507 0 23.66320 0.70731 17.39463 0.51994 4.05779 0.29711 2.98253 0.21836 56358.320416 0.000428 0.15812 0.01235 0.99324 0 23.27125 0.66923 16.92129 0.48659 3.67955 0.26716 2.67583 0.19433 56358.321200 0.000356 0.18402 0.01462 0.99187 0 23.99415 0.74638 17.44660 0.54268 4.41551 0.32289 3.20916 0.23463 56358.321981 0.000425 0.16942 0.01326 0.99320 0 21.80708 0.64735 15.99317 0.47473 3.69461 0.26761 2.70788 0.19614 56358.322791 0.000385 0.16909 0.01343 0.98496 0 24.23767 0.72254 17.61747 0.52519 4.09846 0.30159 2.97472 0.21896 56358.323549 0.000373 0.16310 0.01277 0.99225 0 25.96407 0.75386 18.94108 0.54995 4.23479 0.30798 3.09003 0.22473 56358.324461 0.000538 0.18188 0.01171 0.98309 0 23.96482 0.60630 17.60289 0.44529 4.35874 0.25795 3.20291 0.18955
