/* ** ** 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 55235.212145 0.000472 0.21043 0.01213 0.98931 0 24.28636 0.57894 22.12409 0.52735 5.11049 0.26818 4.65504 0.24428 55235.251223 0.000260 0.21346 0.01690 0.98889 0 23.00523 0.76204 20.91841 0.69287 4.91080 0.35300 4.46497 0.32096 55235.251741 0.000258 0.21657 0.01711 0.98876 0 22.73338 0.75884 20.83740 0.69555 4.92339 0.35258 4.51296 0.32319 55235.252233 0.000234 0.21952 0.01714 1.00000 0 25.07662 0.83875 22.63060 0.75692 5.50488 0.38831 4.97120 0.35064 55235.252977 0.000509 0.20162 0.01145 0.98597 0 23.67550 0.55126 21.59951 0.50293 4.77336 0.24734 4.35642 0.22573 55235.318596 0.000258 0.21043 0.01646 1.00000 0 23.85244 0.78451 21.53368 0.70819 5.01931 0.35625 4.53309 0.32173 55235.319111 0.000258 0.20774 0.01642 0.98876 0 23.93366 0.78309 21.65702 0.70857 4.97186 0.35765 4.49796 0.32351 55235.319600 0.000231 0.22044 0.01748 1.00000 0 25.21675 0.85262 22.54220 0.76223 5.55867 0.39885 4.97280 0.35674 55235.320340 0.000509 0.19927 0.01127 0.99657 0 24.81549 0.56663 22.36415 0.51063 4.94495 0.25577 4.45821 0.23065 55235.385255 0.000258 0.21464 0.01731 1.00000 0 22.67158 0.76078 20.50699 0.68814 4.86613 0.35688 4.39851 0.32265 55235.385810 0.000298 0.18750 0.01457 0.99029 0 23.40155 0.72196 20.91729 0.64526 4.38787 0.31298 3.91635 0.27933 55235.386331 0.000223 0.25752 0.02072 1.00000 0 22.02419 0.80277 20.06505 0.73136 5.67162 0.40679 5.16711 0.37061 55235.387037 0.000483 0.18772 0.01180 0.99121 0 21.98067 0.54458 20.02485 0.49612 4.12628 0.23842 3.75912 0.21720 55235.451385 0.000295 0.20271 0.01599 1.00000 0 21.33602 0.69140 19.15522 0.62069 4.32510 0.31100 3.87813 0.27888 55235.451941 0.000260 0.23759 0.01893 0.98889 0 20.83653 0.72876 18.76881 0.65643 4.95049 0.35449 4.45891 0.31929 55235.452499 0.000298 0.19567 0.01531 0.99029 0 22.17577 0.70025 19.88155 0.62777 4.33924 0.31074 3.89062 0.27860 55235.453107 0.000310 0.19527 0.01514 1.00000 0 21.54735 0.67852 19.21891 0.60514 4.20750 0.29804 3.75134 0.26571 55235.453752 0.000336 0.18151 0.01409 0.99138 0 21.35886 0.64575 19.27318 0.58269 3.87693 0.27710 3.49834 0.25004
