/* ** ** 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 59938.234303 0.000460 0.10544 0.00800 0.98742 0 26.75271 0.62483 23.86304 0.55743 2.82090 0.20353 2.51688 0.18159 59938.235174 0.000411 0.11826 0.00911 0.98592 0 26.46642 0.65739 23.76241 0.59015 3.12996 0.22835 2.81054 0.20499 59938.236033 0.000448 0.10334 0.00814 0.99355 0 26.94450 0.63266 24.11660 0.56620 2.78437 0.20928 2.49426 0.18743 59938.236968 0.000486 0.09890 0.00765 0.98810 0 26.58374 0.60359 23.76374 0.53958 2.62907 0.19431 2.34818 0.17359 59938.237888 0.000434 0.11013 0.00859 0.99333 0 26.30390 0.63570 23.62501 0.57089 2.89675 0.21478 2.60264 0.19293 59938.238782 0.000460 0.10471 0.00804 0.98742 0 26.60635 0.62208 23.80288 0.55653 2.78604 0.20375 2.49345 0.18235 59938.239670 0.000428 0.11558 0.00875 1.00000 0 25.73843 0.63139 23.20828 0.56933 2.97478 0.21319 2.68236 0.19223 59938.240518 0.000420 0.11460 0.00882 0.99310 0 26.55083 0.65128 23.83775 0.58468 3.04285 0.22197 2.73247 0.19929 59938.241325 0.000388 0.12358 0.00939 1.00000 0 26.71324 0.67660 23.97313 0.60720 3.30112 0.23661 2.96260 0.21232 59938.242141 0.000428 0.11175 0.00846 1.00000 0 26.76661 0.64329 24.13388 0.58002 2.99121 0.21470 2.69700 0.19358 59938.242963 0.000394 0.12112 0.00937 0.98529 0 26.84866 0.67447 24.09770 0.60541 3.25202 0.23784 2.92143 0.21364 59938.243776 0.000420 0.11807 0.00917 0.98621 0 25.72753 0.63918 23.09243 0.57367 3.03773 0.22361 2.72471 0.20061 59938.245012 0.000816 0.11492 0.00623 0.99645 0 26.36045 0.46097 23.76936 0.41566 3.02947 0.15548 2.73169 0.14019
