/* ** ** 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 58215.046449 0.000385 0.19082 0.01487 0.98496 0 17.03995 0.52782 16.00260 0.49569 3.25159 0.23246 3.05364 0.21831 58215.047303 0.000469 0.13822 0.01065 0.99383 0 18.87586 0.50393 17.72675 0.47326 2.60896 0.18850 2.45013 0.17702 58215.048200 0.000428 0.16790 0.01305 0.97297 0 17.46188 0.50881 16.39885 0.47783 2.93177 0.21127 2.75329 0.19841 58215.049109 0.000480 0.13518 0.01055 0.99398 0 18.61045 0.49308 17.47750 0.46306 2.51573 0.18474 2.36257 0.17349 58215.050014 0.000425 0.15988 0.01274 0.98639 0 17.76345 0.51545 16.68205 0.48407 2.83997 0.21083 2.66708 0.19800 58215.051267 0.000828 0.16465 0.00914 0.98794 0 17.72651 0.36759 16.64737 0.34521 2.91864 0.15027 2.74096 0.14112 58215.093895 0.000634 0.14008 0.01091 0.98630 0 18.88439 0.51096 12.94564 0.35027 2.64533 0.19324 1.81343 0.13247 58215.095084 0.000556 0.15740 0.01240 0.99479 0 19.01653 0.54599 13.03622 0.37429 2.99319 0.21950 2.05189 0.15047 58215.096181 0.000541 0.15682 0.01226 0.98396 0 19.90315 0.56553 13.64402 0.38768 3.12127 0.22740 2.13970 0.15589 58215.097674 0.000952 0.15227 0.00928 0.98653 0 18.64454 0.41392 12.78122 0.28375 2.83903 0.16117 1.94621 0.11048 58215.161890 0.001962 0.17468 0.00980 0.97198 0 19.91879 0.43029 6.68633 0.14444 3.47946 0.18022 1.16798 0.06050
