/* ** ** 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 56771.264333 0.000532 0.15935 0.01229 0.98370 0 15.18076 0.43039 13.74941 0.38980 2.41911 0.17349 2.19047 0.15710 56771.265326 0.000460 0.17692 0.01390 1.00000 0 15.39475 0.46849 13.98806 0.42566 2.72367 0.19722 2.47598 0.17927 56771.266263 0.000477 0.17517 0.01377 1.00000 0 15.02584 0.45505 13.64415 0.41320 2.63205 0.19096 2.38961 0.17338 56771.267273 0.000532 0.15461 0.01202 0.96739 0 15.85809 0.44200 14.30953 0.39882 2.45174 0.17791 2.21509 0.16072 56771.268306 0.000501 0.17122 0.01323 0.98844 0 14.97201 0.44219 13.59758 0.40158 2.56347 0.18301 2.32674 0.16608 56771.269296 0.000489 0.16973 0.01327 0.98817 0 15.28942 0.45129 13.88305 0.40976 2.59512 0.18791 2.35737 0.17068 56771.270268 0.000483 0.17984 0.01415 0.99401 0 14.59694 0.44478 13.20919 0.40249 2.62517 0.19049 2.37522 0.17234 56771.271258 0.000506 0.16849 0.01311 0.98286 0 15.07539 0.44180 13.63353 0.39955 2.54003 0.18301 2.29696 0.16552 56771.272265 0.000501 0.17212 0.01344 0.99422 0 14.66911 0.43484 13.36434 0.39616 2.52491 0.18235 2.30049 0.16613 56771.273243 0.000477 0.17701 0.01375 0.98788 0 15.26978 0.45533 13.82564 0.41225 2.70284 0.19382 2.44837 0.17552 56771.274339 0.000619 0.16152 0.01135 0.99065 0 15.21245 0.39888 13.81295 0.36218 2.45712 0.16024 2.23299 0.14563
