/* ** ** 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 59196.122158 0.000385 0.20500 0.01676 0.99248 0 20.30082 0.67258 14.38585 0.47467 4.16166 0.31109 2.92535 0.21813 59196.122945 0.000402 0.20758 0.01688 1.00000 0 19.39157 0.64661 13.48553 0.44944 4.02527 0.29860 2.80685 0.20814 59196.123732 0.000385 0.18975 0.01476 0.98496 0 23.07566 0.71751 16.17376 0.50262 4.37850 0.31226 3.06140 0.21823 59196.124484 0.000367 0.20860 0.01735 0.98425 0 20.88899 0.70541 14.63456 0.49400 4.35745 0.33126 3.04560 0.23171 59196.125271 0.000420 0.18195 0.01456 0.97931 0 22.14479 0.68490 15.21594 0.47051 4.02930 0.29726 2.77577 0.20472 59196.126087 0.000396 0.19475 0.01546 0.99270 0 21.29724 0.68234 14.84646 0.47559 4.14757 0.30126 2.89269 0.21002 59196.126842 0.000359 0.20905 0.01674 0.99194 0 21.91622 0.72456 15.35081 0.50730 4.58155 0.33409 3.19996 0.23326 59196.127598 0.000396 0.18628 0.01469 0.99270 0 21.66828 0.67671 15.59771 0.48709 4.03647 0.29229 2.90742 0.21054 59196.128344 0.000350 0.20750 0.01633 0.98347 0 22.83853 0.74383 16.07889 0.52365 4.73891 0.33961 3.33644 0.23905 59196.129033 0.000339 0.23891 0.01896 0.98291 0 20.62415 0.72401 14.51722 0.50938 4.92728 0.35070 3.46828 0.24687 59196.129704 0.000333 0.22671 0.01818 0.99130 0 21.91596 0.75313 15.29415 0.52558 4.96866 0.35993 3.46851 0.25117 59196.130419 0.000382 0.20151 0.01641 0.99242 0 21.00833 0.68803 14.67333 0.48047 4.23346 0.31557 2.94768 0.21979 59196.131371 0.000570 0.21747 0.01352 0.98477 0 21.61557 0.57181 15.18142 0.40156 4.70070 0.26457 3.29608 0.18549
