/* ** ** 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 57379.460818 0.000318 0.15365 0.01183 0.97273 0 25.98018 0.71871 24.09081 0.66644 3.99190 0.28681 3.70144 0.26595 57379.461466 0.000330 0.14596 0.01134 1.00000 0 25.78869 0.71061 23.77736 0.65514 3.76422 0.27335 3.46885 0.25194 57379.462129 0.000333 0.14247 0.01088 0.99130 0 26.40266 0.71187 24.47973 0.66002 3.76160 0.26883 3.48765 0.24925 57379.462823 0.000362 0.13308 0.01013 0.99200 0 26.28379 0.68608 24.24702 0.63292 3.49789 0.25002 3.22630 0.23062 57379.463503 0.000318 0.14716 0.01133 1.00000 0 26.38604 0.72979 24.46614 0.67669 3.88305 0.27900 3.60049 0.25869 57379.464183 0.000362 0.13012 0.00993 0.99200 0 26.47361 0.68221 24.54608 0.63254 3.44480 0.24751 3.19399 0.22949 57379.464892 0.000347 0.14454 0.01092 0.98333 0 25.46040 0.68741 23.60817 0.63740 3.68017 0.25958 3.41245 0.24070 57379.465581 0.000341 0.14205 0.01112 0.99153 0 25.43024 0.69392 23.45186 0.63993 3.61246 0.26513 3.33252 0.24463 57379.466301 0.000379 0.13670 0.00990 0.98834 0 26.83194 0.67611 24.70620 0.62248 3.66790 0.24906 3.37673 0.22929 57379.517782 0.000336 0.14694 0.01116 1.00000 0 25.41225 0.69612 23.63695 0.64749 3.73420 0.26438 3.47344 0.24592 57379.518448 0.000330 0.14073 0.01076 0.98246 0 27.23425 0.72489 25.34068 0.67449 3.83263 0.27477 3.56616 0.25566 57379.519081 0.000304 0.14818 0.01137 0.99048 0 27.68651 0.76388 25.77102 0.71103 4.10264 0.29378 3.81882 0.27346 57379.519727 0.000341 0.13832 0.01108 0.99153 0 25.68495 0.69462 23.66532 0.63996 3.55280 0.26780 3.27455 0.24675 57379.520395 0.000327 0.15432 0.01186 0.98230 0 25.07022 0.69965 23.19919 0.64743 3.86889 0.27709 3.57800 0.25621 57379.521046 0.000324 0.13899 0.01075 1.00000 0 27.17154 0.73310 25.28733 0.68226 3.77663 0.27388 3.51472 0.25489 57379.521726 0.000356 0.13373 0.01048 1.00000 0 25.50255 0.67801 23.73392 0.63099 3.41040 0.25141 3.17390 0.23397 57379.522412 0.000330 0.14338 0.01109 0.99123 0 26.40171 0.72136 24.42971 0.66745 3.78540 0.27386 3.50135 0.25326 57379.523155 0.000414 0.14572 0.01016 0.99301 0 25.57559 0.62807 23.80349 0.58455 3.72693 0.24318 3.46873 0.22633
