/* ** ** 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 55713.962935 0.000472 0.11386 0.01700 0.98773 0 6.16534 0.29503 5.47682 0.26207 0.70198 0.09928 0.62215 0.08799 55713.963956 0.000550 0.09540 0.01430 0.96842 0 6.37376 0.28100 5.64461 0.24884 0.60805 0.08711 0.53878 0.07719 55713.964951 0.000446 0.11784 0.01767 0.99351 0 6.29144 0.30646 5.60894 0.27321 0.74136 0.10514 0.66104 0.09375 55713.965825 0.000428 0.13099 0.01996 0.96622 0 5.93548 0.30766 5.29290 0.27435 0.77751 0.11139 0.69326 0.09932 55713.966754 0.000501 0.09970 0.01480 0.98266 0 6.68343 0.30070 5.91390 0.26605 0.66636 0.09424 0.58922 0.08333 55713.967691 0.000437 0.11548 0.01726 0.97351 0 6.64806 0.32070 5.90015 0.28462 0.76772 0.10858 0.68141 0.09637 55713.968551 0.000422 0.13149 0.02001 0.95890 0 6.04149 0.30964 5.38587 0.27604 0.79439 0.11381 0.70811 0.10145 55713.969341 0.000367 0.14723 0.02235 0.98425 0 6.15743 0.33999 5.43015 0.29982 0.90656 0.12822 0.80133 0.11333 55713.970189 0.000480 0.11057 0.01652 0.97590 0 6.43982 0.30289 5.65473 0.26594 0.71207 0.10098 0.62432 0.08854 55713.971204 0.000535 0.09853 0.01516 0.98378 0 6.10071 0.27633 5.41195 0.24512 0.60109 0.08840 0.53338 0.07845 55713.972228 0.000489 0.10778 0.01589 0.98225 0 6.42967 0.29659 5.70402 0.26313 0.69297 0.09704 0.61548 0.08618 55713.973108 0.000391 0.12943 0.01970 0.97037 0 6.60375 0.33888 5.85648 0.30053 0.85473 0.12245 0.75676 0.10842 55713.973950 0.000451 0.12524 0.01928 0.98718 0 5.73425 0.29409 5.08375 0.26073 0.71816 0.10426 0.63705 0.09247 55713.975047 0.000645 0.11857 0.01570 0.97758 0 5.66200 0.24350 5.00636 0.21527 0.67134 0.08410 0.59260 0.07424
