/* ** ** 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 57430.311685 0.000391 0.09560 0.01434 0.98519 0 8.74570 0.38866 7.78602 0.34598 0.83606 0.11974 0.74550 0.10678 57430.312637 0.000561 0.06856 0.01004 0.96392 0 8.78511 0.32214 7.88217 0.28904 0.60231 0.08540 0.54094 0.07670 57430.313716 0.000518 0.07489 0.01099 0.99441 0 8.33924 0.32736 7.51386 0.29496 0.62455 0.08832 0.56273 0.07958 57430.314789 0.000556 0.07450 0.01092 0.96875 0 8.07189 0.31251 7.22235 0.27961 0.60133 0.08504 0.53853 0.07616 57430.315762 0.000417 0.09553 0.01435 0.98611 0 8.19070 0.36042 7.38164 0.32482 0.78249 0.11235 0.70522 0.10126 57430.316673 0.000495 0.07704 0.01159 0.98246 0 8.41589 0.33693 7.58281 0.30358 0.64833 0.09406 0.58415 0.08475 57430.317758 0.000590 0.06621 0.00967 0.99020 0 8.30907 0.30464 7.48901 0.27458 0.55015 0.07780 0.49588 0.07013 57430.318887 0.000538 0.07247 0.01074 0.96237 0 8.50131 0.32540 7.63221 0.29212 0.61605 0.08824 0.55392 0.07934 57430.319978 0.000553 0.06869 0.00997 0.98953 0 8.83261 0.32347 7.93364 0.29054 0.60674 0.08518 0.54581 0.07662 57430.321378 0.000848 0.08603 0.00929 0.98635 0 8.62778 0.25989 7.74078 0.23316 0.74224 0.07695 0.66529 0.06898
