/* ** ** 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 56667.418419 0.000501 0.17429 0.01338 0.99422 0 14.59329 0.43575 13.36376 0.39902 2.54340 0.17986 2.32946 0.16472 56667.419490 0.000570 0.15165 0.01178 0.99492 0 14.49957 0.40568 13.26577 0.37114 2.19886 0.15936 2.00926 0.14560 56667.420598 0.000538 0.16449 0.01263 0.99462 0 14.24995 0.41250 13.10931 0.37948 2.34395 0.16676 2.15650 0.15342 56667.421741 0.000605 0.15086 0.01178 0.98086 0 13.88126 0.38726 12.67394 0.35357 2.09407 0.15270 1.91269 0.13946 56667.422855 0.000509 0.16745 0.01291 0.98864 0 14.95860 0.43505 13.73248 0.39936 2.50481 0.17886 2.29450 0.16382 56667.423874 0.000509 0.16703 0.01306 1.00000 0 14.67509 0.43179 13.38574 0.39383 2.45117 0.17764 2.23758 0.16215 56667.424895 0.000512 0.16857 0.01290 0.98870 0 15.01099 0.43637 13.66584 0.39726 2.53042 0.17915 2.30263 0.16300 56667.425908 0.000501 0.17533 0.01377 0.99422 0 14.31399 0.43271 13.03701 0.39407 2.50962 0.18191 2.28962 0.16592 56667.427100 0.000692 0.19530 0.01238 0.98673 0 14.29331 0.36566 13.05658 0.33400 2.79154 0.16194 2.55093 0.14798 56667.502712 0.000573 0.15323 0.01206 0.99495 0 14.23405 0.40396 12.96667 0.36793 2.18115 0.16004 1.98938 0.14589 56667.503814 0.000518 0.16665 0.01310 0.99441 0 14.44609 0.42544 13.27452 0.39092 2.40749 0.17542 2.21181 0.16115 56667.504934 0.000602 0.15493 0.01158 0.99519 0 14.57438 0.39763 13.40022 0.36560 2.25806 0.15719 2.07614 0.14453
