/* ** ** 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 56761.447375 0.000587 0.14668 0.01111 0.98030 0 15.17643 0.41181 13.73666 0.37270 2.22609 0.15742 2.01340 0.14237 56761.448492 0.000530 0.15396 0.01167 0.98361 0 15.95960 0.44239 14.53048 0.40278 2.45713 0.17331 2.23706 0.15779 56761.449629 0.000608 0.13913 0.01071 1.00000 0 14.85377 0.39851 13.52747 0.36293 2.06664 0.14904 1.88211 0.13573 56761.450841 0.000605 0.13472 0.01046 0.98086 0 15.57026 0.40886 14.18003 0.37235 2.09767 0.15329 1.91037 0.13960 56761.452074 0.000628 0.12820 0.00987 0.98618 0 15.74630 0.40311 14.34026 0.36712 2.01874 0.14655 1.83848 0.13346 56761.453266 0.000564 0.15139 0.01163 0.98974 0 14.92182 0.41401 13.58938 0.37704 2.25897 0.16184 2.05726 0.14739 56761.454479 0.000648 0.13260 0.01005 0.99554 0 14.81080 0.38549 13.48849 0.35107 1.96395 0.13979 1.78861 0.12731 56761.455752 0.000625 0.13261 0.01029 0.99074 0 15.15339 0.39625 13.80040 0.36087 2.00945 0.14684 1.83003 0.13373 56761.456964 0.000587 0.14203 0.01087 0.98522 0 15.34773 0.41229 13.97738 0.37548 2.17989 0.15618 1.98525 0.14223 56761.458139 0.000587 0.14769 0.01158 0.98030 0 14.67915 0.40649 13.33249 0.36916 2.16797 0.15905 1.96895 0.14445 56761.459551 0.000825 0.12281 0.00849 0.99649 0 15.29393 0.34656 13.92854 0.31562 1.87818 0.12273 1.71050 0.11177
