/* ** ** 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 59175.131882 0.000556 0.13806 0.01055 0.98438 0 17.30618 0.45573 15.29036 0.40266 2.38928 0.17141 2.11258 0.15155 59175.132932 0.000495 0.15094 0.01183 0.99415 0 17.17299 0.48354 15.34973 0.43221 2.59215 0.18961 2.31695 0.16948 59175.133890 0.000463 0.15553 0.01193 0.99375 0 18.16174 0.51352 16.21881 0.45859 2.82472 0.20133 2.52249 0.17979 59175.134833 0.000480 0.15449 0.01227 1.00000 0 16.93569 0.48720 15.13247 0.43532 2.61634 0.19368 2.33781 0.17306 59175.135762 0.000448 0.17620 0.01360 0.99355 0 16.53626 0.50018 14.77339 0.44685 2.91362 0.20685 2.60306 0.18480 59175.136679 0.000469 0.14937 0.01177 1.00000 0 18.13342 0.50937 16.20270 0.45514 2.70861 0.19942 2.42027 0.17820 59175.137617 0.000469 0.15392 0.01207 0.99383 0 17.68707 0.50353 15.80580 0.44997 2.72237 0.19890 2.43276 0.17774 59175.138583 0.000498 0.14472 0.01125 0.99419 0 17.89392 0.49219 15.98752 0.43975 2.58960 0.18819 2.31392 0.16816 59175.139506 0.000425 0.18835 0.01466 0.96599 0 16.69897 0.51582 14.92146 0.46092 3.14519 0.22474 2.81037 0.20082 59175.140392 0.000460 0.15184 0.01182 1.00000 0 18.22876 0.51313 16.29841 0.45879 2.76790 0.20090 2.47467 0.17962 59175.141607 0.000755 0.15819 0.01009 0.98467 0 16.12859 0.37897 14.41384 0.33868 2.55139 0.15134 2.28015 0.13525
