/* ** ** 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 56072.708343 0.000382 0.12969 0.00989 1.00000 0 25.00548 0.64290 23.21653 0.59689 3.24300 0.23286 3.01221 0.21630 56072.709078 0.000353 0.14054 0.01069 1.00000 0 25.01601 0.67379 23.27591 0.62691 3.51582 0.25010 3.27033 0.23264 56072.709818 0.000388 0.13642 0.01032 0.98507 0 23.90045 0.62647 22.26825 0.58369 3.26054 0.23135 3.03776 0.21555 56072.710588 0.000382 0.12951 0.00983 1.00000 0 25.21175 0.64777 23.49277 0.60361 3.26519 0.23327 3.04256 0.21736 56072.711369 0.000399 0.12479 0.00980 1.00000 0 24.27703 0.62413 22.48314 0.57799 3.02943 0.22483 2.80563 0.20819 56072.712185 0.000417 0.11995 0.00924 1.00000 0 24.56228 0.61394 22.72615 0.56801 2.94632 0.21467 2.72386 0.19848 56072.713053 0.000451 0.11238 0.00862 0.98077 0 24.48030 0.58754 22.81225 0.54751 2.75109 0.20047 2.56363 0.18681 56072.713945 0.000440 0.10900 0.00829 1.00000 0 25.79388 0.61039 24.03590 0.56879 2.81166 0.20327 2.62003 0.18942 56072.714763 0.000379 0.13371 0.01051 1.00000 0 23.84391 0.63399 22.21927 0.59079 3.18807 0.23592 2.97084 0.21985 56072.715507 0.000365 0.13487 0.01017 1.00000 0 25.30080 0.66208 23.57697 0.61697 3.41240 0.24129 3.17990 0.22485 56072.716312 0.000440 0.11416 0.00878 1.00000 0 24.62180 0.60015 22.75739 0.55467 2.81086 0.20491 2.59576 0.18928 56072.717203 0.000451 0.11496 0.00878 0.99359 0 23.72252 0.57749 22.10613 0.53815 2.72725 0.19753 2.54143 0.18407 56072.718187 0.000532 0.11603 0.00781 0.99457 0 25.44390 0.55115 23.63331 0.51192 2.95234 0.18826 2.74199 0.17486
