/* ** ** 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 58113.291819 0.000509 0.13061 0.01012 0.98295 0 19.63272 0.51192 17.41458 0.45407 2.56417 0.18701 2.27453 0.16588 58113.292806 0.000477 0.13975 0.01065 0.99394 0 19.53659 0.52499 17.49675 0.47018 2.73030 0.19466 2.44514 0.17433 58113.293735 0.000451 0.13428 0.01064 0.99359 0 20.70934 0.55403 18.54497 0.49612 2.78078 0.20751 2.49022 0.18583 58113.294629 0.000443 0.15427 0.01190 1.00000 0 18.77876 0.53465 16.81871 0.47884 2.89698 0.20761 2.59474 0.18595 58113.295532 0.000460 0.14531 0.01129 0.99371 0 19.13277 0.52922 17.13204 0.47388 2.78012 0.20193 2.48940 0.18081 58113.296434 0.000443 0.15305 0.01193 0.99346 0 18.88487 0.53514 16.90765 0.47911 2.89038 0.20994 2.58766 0.18795 58113.297314 0.000437 0.14270 0.01106 0.99338 0 20.52216 0.55679 18.37507 0.49854 2.92853 0.21271 2.62217 0.19045 58113.298220 0.000469 0.13637 0.01055 0.99383 0 20.00075 0.53382 17.91502 0.47815 2.72744 0.19810 2.44301 0.17744 58113.299444 0.000755 0.15016 0.00871 0.98863 0 20.04575 0.42088 17.95509 0.37699 3.01007 0.16275 2.69603 0.14577 58113.338642 0.000538 0.13192 0.01043 0.98387 0 18.34617 0.48620 15.92330 0.42098 2.42025 0.18030 2.12177 0.15767 58113.339970 0.000790 0.14197 0.00860 0.99634 0 18.96481 0.40138 16.79976 0.35555 2.69252 0.15274 2.38499 0.13530
