/* ** ** 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 56346.347609 0.000292 0.08108 0.01224 1.00000 0 13.65012 0.56293 11.99858 0.49478 1.10676 0.16079 0.97374 0.14141 56346.348926 0.001024 0.09184 0.00696 0.97458 0 14.05505 0.30560 12.38601 0.26928 1.29082 0.09374 1.14026 0.08279 56346.350943 0.000992 0.09507 0.00717 0.99125 0 14.03953 0.31128 12.22415 0.27101 1.33475 0.09628 1.16238 0.08384 56346.352933 0.000998 0.10134 0.00767 0.99130 0 12.96607 0.29616 11.41026 0.26061 1.31404 0.09475 1.15558 0.08335 56346.354930 0.000998 0.09581 0.00730 0.98841 0 13.78924 0.30630 12.05087 0.26767 1.32109 0.09632 1.15418 0.08414 56346.357462 0.001534 0.09130 0.00568 0.98491 0 13.97210 0.24880 12.16853 0.21668 1.27572 0.07610 1.11089 0.06626
