/* ** ** 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 55178.230394 0.000255 0.16775 0.01297 1.00000 0 28.92040 0.84526 26.90655 0.78640 4.85145 0.34736 4.51347 0.32316 55178.230915 0.000266 0.16468 0.01341 1.00000 0 27.07509 0.80846 25.18114 0.75191 4.45876 0.33791 4.14694 0.31428 55178.231421 0.000240 0.18276 0.01449 1.00000 0 27.92683 0.86015 25.98927 0.80047 5.10394 0.37274 4.74974 0.34687 55178.232055 0.000394 0.18583 0.01468 0.60296 0 27.77434 0.85439 25.85393 0.79531 5.16122 0.37556 4.80434 0.34960 55178.232732 0.000284 0.15033 0.01182 1.00000 0 28.45665 0.80060 26.48889 0.74524 4.27777 0.31408 3.98186 0.29235 55178.233282 0.000266 0.17480 0.01366 1.00000 0 26.41220 0.79886 24.58963 0.74373 4.61690 0.33264 4.29831 0.30969 55178.233774 0.000226 0.19243 0.01532 1.00000 0 28.04873 0.89460 26.11369 0.83289 5.39754 0.39380 5.02517 0.36664 55178.234245 0.000246 0.17521 0.01373 1.00000 0 28.74739 0.86689 26.57231 0.80128 5.03685 0.36428 4.65538 0.33664 55178.234728 0.000237 0.18833 0.01459 1.00000 0 28.13231 0.87328 25.94238 0.80534 5.29824 0.37611 4.88938 0.34702 55178.235223 0.000258 0.16937 0.01318 1.00000 0 28.83535 0.85220 26.51169 0.78335 4.88384 0.35147 4.49117 0.32309 55178.235744 0.000263 0.17186 0.01352 0.98901 0 27.90496 0.82774 25.62442 0.76002 4.79587 0.34934 4.40258 0.32067 55178.236271 0.000263 0.16399 0.01282 1.00000 0 28.84433 0.83999 26.53413 0.77270 4.73018 0.34330 4.35131 0.31580 55178.236777 0.000243 0.18035 0.01408 0.98810 0 28.75291 0.87637 26.52209 0.80833 5.18559 0.37273 4.78853 0.34412 55178.237283 0.000263 0.16845 0.01296 0.98901 0 28.63030 0.83879 26.29511 0.77030 4.82264 0.34317 4.43251 0.31539 55178.237764 0.000217 0.20356 0.01611 1.00000 0 28.10305 0.91681 26.03888 0.84946 5.72067 0.41263 5.30281 0.38246 55178.238244 0.000263 0.16620 0.01283 0.98901 0 29.10168 0.84494 26.83517 0.77909 4.83677 0.34582 4.46061 0.31891 55178.238748 0.000240 0.17677 0.01398 1.00000 0 28.87978 0.88151 26.69254 0.81471 5.10519 0.37247 4.72245 0.34455 55178.239219 0.000231 0.18879 0.01513 1.00000 0 27.97855 0.88203 25.84171 0.81466 5.28217 0.38908 4.88106 0.35966 55178.239702 0.000252 0.16994 0.01316 1.00000 0 29.16452 0.86605 27.15266 0.80631 4.95632 0.35435 4.61442 0.32991 55178.240186 0.000231 0.18974 0.01483 1.00000 0 28.33941 0.88899 26.17802 0.82115 5.37703 0.38504 4.96482 0.35548 55178.240663 0.000246 0.18122 0.01444 1.00000 0 27.65825 0.85279 25.50535 0.78641 5.01231 0.36837 4.61751 0.33933 55178.241279 0.000370 0.17730 0.01116 1.00000 0 29.06097 0.71011 26.79998 0.65484 5.15236 0.29885 4.75047 0.27557
