/* ** ** 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 57505.961236 0.000255 0.20877 0.01651 0.98864 0 23.60631 0.76890 21.74890 0.70840 4.92829 0.35510 4.54138 0.32722 57505.961789 0.000298 0.17988 0.01385 0.99029 0 23.85091 0.71785 21.86862 0.65814 4.29025 0.30403 3.93411 0.27879 57505.962388 0.000301 0.17870 0.01385 1.00000 0 23.49667 0.71104 21.55578 0.65230 4.19888 0.29961 3.85095 0.27476 57505.962978 0.000289 0.18982 0.01498 1.00000 0 22.52983 0.70896 20.74098 0.65267 4.27659 0.30960 3.93709 0.28502 57505.963583 0.000315 0.18091 0.01403 0.98165 0 22.32649 0.67779 20.55471 0.62400 4.03905 0.28830 3.71854 0.26542 57505.964196 0.000298 0.18964 0.01499 0.99029 0 22.18116 0.68991 20.41687 0.63503 4.20643 0.30579 3.87188 0.28147 57505.964795 0.000301 0.17719 0.01382 1.00000 0 23.53284 0.71332 21.52876 0.65258 4.16982 0.29972 3.81830 0.27441 57505.965409 0.000312 0.17256 0.01325 0.99074 0 23.60698 0.69953 21.73340 0.64401 4.07356 0.28867 3.75027 0.26576 57505.965987 0.000266 0.22171 0.01753 0.98913 0 21.61190 0.72850 19.75993 0.66601 4.79161 0.34277 4.37907 0.31323 57505.966554 0.000301 0.18698 0.01449 1.00000 0 22.42964 0.69494 20.53251 0.63616 4.19396 0.29795 3.83919 0.27275 57505.967159 0.000304 0.17595 0.01368 0.99048 0 23.80911 0.71498 21.67598 0.65089 4.18918 0.30050 3.81242 0.27340 57505.967732 0.000269 0.19116 0.01496 0.98925 0 24.50927 0.76910 22.54167 0.70735 4.68511 0.33598 4.30970 0.30906 57505.968293 0.000292 0.19614 0.01538 0.99010 0 21.96599 0.69553 20.21472 0.64007 4.30851 0.30898 3.96492 0.28434 57505.968884 0.000298 0.18315 0.01429 1.00000 0 22.83158 0.70062 21.01808 0.64497 4.18157 0.29988 3.84944 0.27606 57505.969480 0.000298 0.18293 0.01413 0.99029 0 23.40366 0.71126 21.53907 0.65459 4.28121 0.30404 3.94010 0.27981 57505.970105 0.000327 0.17082 0.01326 1.00000 0 22.31957 0.66234 20.54060 0.60955 3.81269 0.27342 3.50878 0.25163 57505.970727 0.000295 0.17996 0.01398 1.00000 0 23.75280 0.72021 21.85151 0.66256 4.27464 0.30563 3.93245 0.28116 57505.971311 0.000289 0.19529 0.01531 0.99000 0 22.59409 0.71088 20.65556 0.64986 4.41237 0.31692 4.03756 0.29002 57505.971881 0.000281 0.19694 0.01531 1.00000 0 22.99887 0.72835 21.02976 0.66593 4.52949 0.32169 4.14320 0.29423 57505.972527 0.000365 0.19062 0.01339 0.99206 0 22.26491 0.62654 20.48161 0.57635 4.24424 0.27324 3.90427 0.25135
