/* ** ** 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 59287.120927 0.000385 0.16697 0.01290 0.98496 0 20.59022 0.59938 18.16356 0.52870 3.43801 0.24608 3.03006 0.21689 59287.121679 0.000367 0.16489 0.01282 1.00000 0 21.48182 0.62972 18.92429 0.55475 3.54204 0.25500 3.12169 0.22471 59287.122403 0.000356 0.17890 0.01407 1.00000 0 20.15212 0.61623 17.86925 0.54642 3.60523 0.26126 3.19682 0.23166 59287.123129 0.000370 0.16677 0.01287 0.99219 0 21.24096 0.62086 18.83620 0.55057 3.54234 0.25292 3.14127 0.22428 59287.123890 0.000391 0.15752 0.01227 0.99259 0 21.01210 0.59908 18.62909 0.53114 3.30981 0.23985 2.93439 0.21265 59287.124639 0.000359 0.18871 0.01461 0.98387 0 19.74335 0.60789 17.50213 0.53888 3.72579 0.26467 3.30285 0.23462 59287.125363 0.000365 0.18495 0.01437 0.98413 0 19.79389 0.60392 17.54871 0.53542 3.66095 0.26150 3.24568 0.23184 59287.126072 0.000344 0.18029 0.01410 0.97479 0 21.28108 0.64223 18.86077 0.56919 3.83682 0.27690 3.40044 0.24541 59287.127096 0.000680 0.17078 0.00972 0.98923 0 21.09898 0.45780 18.71022 0.40597 3.60333 0.18965 3.19538 0.16818
