/* ** ** 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 54843.808113 0.000205 0.22865 0.01802 0.98592 0 28.33747 0.95910 25.18798 0.85241 6.47938 0.46121 5.75599 0.40952 54843.808526 0.000208 0.21837 0.01716 1.00000 0 28.70331 0.96714 25.50188 0.85928 6.26780 0.44513 5.56654 0.39534 54843.808957 0.000223 0.20972 0.01692 1.00000 0 27.32984 0.90923 24.23930 0.80641 5.73157 0.42133 5.08312 0.37367 54843.809389 0.000208 0.26101 0.02120 0.97214 0 24.43527 0.90840 21.62475 0.80392 6.37789 0.46047 5.64378 0.40743 54843.809802 0.000205 0.23697 0.01875 1.00000 0 27.78518 0.96442 24.16874 0.83880 6.58421 0.46809 5.73312 0.40756 54843.810231 0.000223 0.21851 0.01728 1.00000 0 27.05191 0.91436 23.72034 0.80183 5.91118 0.42276 5.18069 0.37047 54843.810792 0.000339 0.21318 0.01404 0.99917 0 26.22119 0.72565 23.09323 0.63905 5.58986 0.33402 4.92251 0.29409 54843.938667 0.000223 0.21254 0.01694 1.00000 0 28.41748 0.94687 24.14220 0.80443 6.03983 0.43742 5.13556 0.37184 54843.939061 0.000171 0.27315 0.02215 0.98305 0 28.70909 1.07490 25.10314 0.93992 7.84191 0.56407 6.84907 0.49266 54843.939446 0.000214 0.21918 0.01727 1.00000 0 27.91036 0.94215 24.59085 0.83010 6.11746 0.43542 5.38998 0.38363 54843.939865 0.000205 0.23720 0.01880 1.00000 0 27.18386 0.95248 23.93319 0.83858 6.44814 0.45846 5.67691 0.40362 54843.940267 0.000197 0.24476 0.01942 1.00000 0 27.40385 0.96974 24.08154 0.85217 6.70733 0.47620 5.89502 0.41852 54843.940667 0.000203 0.23679 0.01903 1.00000 0 27.35239 0.96934 23.85021 0.84508 6.47674 0.46718 5.64633 0.40720 54843.941089 0.000220 0.21555 0.01706 1.00000 0 27.54075 0.92632 24.23674 0.81519 5.93641 0.42531 5.22435 0.37430 54843.941538 0.000229 0.21199 0.01710 0.96203 0 27.65522 0.90982 24.33190 0.80049 5.86275 0.43178 5.15814 0.37989 54843.942012 0.000246 0.20650 0.01656 0.98824 0 25.64728 0.84633 22.57705 0.74501 5.29618 0.38702 4.66223 0.34069 54843.942458 0.000200 0.24179 0.01924 1.00000 0 27.31588 0.96627 24.03926 0.85036 6.60464 0.47077 5.81242 0.41431 54843.942871 0.000214 0.22564 0.01764 1.00000 0 27.68461 0.93798 24.36863 0.82564 6.24665 0.44017 5.49826 0.38744 54843.943294 0.000208 0.22208 0.01786 1.00000 0 27.96843 0.95151 24.61805 0.83753 6.21121 0.45267 5.46709 0.39845 54843.943702 0.000200 0.23654 0.01910 1.00000 0 27.39030 0.96956 24.10394 0.85323 6.47902 0.47035 5.70196 0.41393 54843.944174 0.000272 0.25102 0.01693 1.00000 0 27.54887 0.82723 24.25486 0.72832 6.91545 0.41766 6.08849 0.36772
