/* ** ** 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 59724.912950 0.000284 0.17445 0.01360 0.98980 0 25.76703 0.77134 23.45401 0.70204 4.49514 0.32352 4.09387 0.29467 59724.913514 0.000281 0.18284 0.01417 1.00000 0 24.69260 0.75745 22.50969 0.69045 4.51482 0.32142 4.11146 0.29270 59724.914044 0.000249 0.21130 0.01662 1.00000 0 24.09121 0.79928 22.06462 0.73204 5.09057 0.36302 4.66237 0.33248 59724.914579 0.000286 0.17918 0.01431 0.98990 0 24.35213 0.74678 22.30622 0.68404 4.36344 0.32186 3.99683 0.29482 59724.915146 0.000281 0.17192 0.01359 1.00000 0 25.89406 0.78119 23.71927 0.71558 4.45171 0.32528 4.07781 0.29796 59724.915708 0.000281 0.18400 0.01434 0.98969 0 24.79346 0.76139 22.70833 0.69735 4.56194 0.32668 4.17825 0.29920 59724.916266 0.000278 0.17833 0.01410 1.00000 0 25.21618 0.78034 23.09577 0.71472 4.49687 0.32724 4.11874 0.29972 59724.916854 0.000310 0.16701 0.01308 1.00000 0 24.14998 0.71555 22.11858 0.65536 4.03319 0.29228 3.69393 0.26770 59724.917432 0.000269 0.18997 0.01484 1.00000 0 24.65862 0.77488 22.58188 0.70962 4.68441 0.33490 4.28990 0.30670 59724.918023 0.000321 0.16301 0.01242 1.00000 0 24.54986 0.70922 22.48390 0.64954 4.00185 0.28205 3.66509 0.25832 59724.918619 0.000275 0.18842 0.01477 1.00000 0 24.21133 0.76755 22.17631 0.70303 4.56191 0.32698 4.17850 0.29950 59724.919174 0.000281 0.17841 0.01398 1.00000 0 24.92741 0.76218 22.83044 0.69807 4.44729 0.32094 4.07322 0.29395 59724.919733 0.000278 0.18048 0.01425 1.00000 0 24.78414 0.76662 22.69744 0.70208 4.47293 0.32500 4.09633 0.29764 59724.920291 0.000281 0.18863 0.01467 0.98969 0 24.17634 0.75089 22.14180 0.68770 4.56045 0.32521 4.17671 0.29785 59724.920855 0.000284 0.19525 0.01520 0.98980 0 23.23174 0.73376 21.27635 0.67200 4.53603 0.32265 4.15430 0.29550 59724.921671 0.000532 0.18390 0.01042 1.00000 0 24.39411 0.54585 22.34159 0.49992 4.48614 0.23365 4.10869 0.21399
