/* ** ** 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 55210.361211 0.000509 0.22912 0.00820 1.00000 0 53.63929 0.82276 49.26477 0.75558 12.29004 0.39724 11.28574 0.36479 55210.362227 0.000506 0.22390 0.00795 1.00000 0 55.50591 0.84468 50.72501 0.77188 12.42770 0.39870 11.35943 0.36446 55210.363222 0.000489 0.23951 0.00857 1.00000 0 53.93364 0.84712 49.17691 0.77235 12.91739 0.41546 11.78759 0.37912 55210.364194 0.000483 0.24732 0.00881 1.00000 0 52.78425 0.84292 48.33565 0.77185 13.05450 0.41578 11.95580 0.38073 55210.365126 0.000448 0.26084 0.00946 1.00000 0 53.39096 0.88269 48.94479 0.80917 13.92634 0.44952 12.76180 0.41194 55210.366037 0.000463 0.25164 0.00898 1.00000 0 54.37712 0.87379 49.72470 0.79898 13.68361 0.43595 12.51079 0.39859 55210.367004 0.000503 0.22522 0.00829 1.00000 0 54.17573 0.84122 49.54916 0.76935 12.20153 0.40736 11.15743 0.37260 55210.367993 0.000486 0.23649 0.00888 1.00000 0 53.10960 0.85448 48.57430 0.78156 12.56008 0.42636 11.48905 0.39009 55210.368954 0.000475 0.24442 0.00938 0.99390 0 52.01562 0.85302 47.74706 0.78304 12.71366 0.44104 11.67423 0.40484 55210.369886 0.000457 0.25075 0.00937 1.00000 0 53.41158 0.88020 49.03461 0.80802 13.39279 0.44930 12.29550 0.41254 55210.370809 0.000466 0.24319 0.00896 1.00000 0 55.05021 0.89067 49.76674 0.80511 13.38773 0.44321 12.10567 0.40068 55210.371787 0.000512 0.21935 0.00808 0.99435 0 55.24382 0.84349 50.17070 0.76599 12.11762 0.40592 11.00274 0.36856 55210.372762 0.000463 0.25986 0.00950 0.99375 0 52.38309 0.86148 47.73076 0.78490 13.61205 0.44464 12.40666 0.40524 55210.373685 0.000460 0.24594 0.00892 1.00000 0 54.95803 0.87953 50.40015 0.80652 13.51620 0.44015 12.39283 0.40363 55210.374912 0.000767 0.24680 0.00703 1.00000 0 53.20769 0.67128 48.58598 0.61290 13.13147 0.33561 11.98816 0.30640
