/* ** ** 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 58152.929600 0.000396 0.27824 0.01027 0.99270 0 62.83408 1.07890 52.03674 0.89203 17.48318 0.57144 14.46760 0.47195 58152.930396 0.000399 0.26104 0.00959 1.00000 0 64.20941 1.07060 54.63134 0.91088 16.76117 0.54891 14.25831 0.46679 58152.931195 0.000399 0.24827 0.00894 1.00000 0 66.96657 1.07892 57.86106 0.93221 16.62574 0.53537 14.36584 0.46260 58152.931999 0.000405 0.25058 0.00908 1.00000 0 65.75802 1.05956 56.50777 0.91050 16.47732 0.53471 14.14706 0.45909 58152.932795 0.000391 0.24913 0.00909 1.00000 0 67.69691 1.09668 58.47602 0.94730 16.86522 0.55129 14.56754 0.47619 58152.933553 0.000367 0.27615 0.01022 1.00000 0 65.22680 1.11392 56.00346 0.95641 18.01228 0.59120 15.46983 0.50777 58152.934294 0.000373 0.27096 0.00992 1.00000 0 65.76418 1.11504 56.72010 0.96170 17.81976 0.57798 15.36893 0.49848 58152.935040 0.000373 0.27045 0.00985 0.98450 0 67.19709 1.13044 57.76151 0.97153 18.17340 0.58706 15.62632 0.50475 58152.935801 0.000388 0.26025 0.00955 1.00000 0 65.35783 1.08572 56.41648 0.93718 17.00941 0.55688 14.68393 0.48073 58152.936577 0.000388 0.25674 0.00950 1.00000 0 65.64757 1.09180 56.70427 0.94305 16.85462 0.55728 14.55744 0.48134 58152.937329 0.000365 0.27476 0.01026 1.00000 0 65.96956 1.13771 56.31887 0.97131 18.12572 0.60059 15.47399 0.51269 58152.938081 0.000388 0.25728 0.00950 1.00000 0 65.83766 1.09678 56.93180 0.94841 16.93862 0.55825 14.64715 0.48273 58152.938822 0.000353 0.28747 0.01057 1.00000 0 65.39805 1.13996 56.49820 0.98482 18.79982 0.60883 16.24233 0.52600 58152.939560 0.000385 0.26191 0.00962 1.00000 0 65.89759 1.10067 56.46526 0.94304 17.25917 0.56423 14.78660 0.48335 58152.940443 0.000498 0.25695 0.00831 1.00000 0 67.40586 0.97467 58.07504 0.83978 17.31964 0.50103 14.91822 0.43162
