/* ** ** 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 55939.173463 0.000344 0.10820 0.01596 1.00000 0 9.18769 0.42552 7.92800 0.36713 0.99415 0.13923 0.85857 0.12022 55939.174189 0.000382 0.10352 0.01553 0.92424 0 9.12559 0.40662 7.84300 0.34944 0.94469 0.13534 0.81264 0.11642 55939.174947 0.000376 0.09594 0.01475 1.00000 0 8.97813 0.40497 7.78583 0.35119 0.86132 0.12664 0.74686 0.10982 55939.175714 0.000391 0.09660 0.01429 0.94815 0 9.35069 0.40455 8.10132 0.35049 0.90327 0.12774 0.78255 0.11067 55939.176411 0.000307 0.12258 0.01837 0.99057 0 9.03731 0.44901 7.77419 0.38623 1.10776 0.15667 0.95397 0.13491 55939.177624 0.000906 0.12626 0.01113 0.97444 0 8.94104 0.25985 7.74786 0.22518 1.12886 0.09393 0.97822 0.08140 55939.178897 0.000367 0.10118 0.01504 1.00000 0 9.03625 0.41279 7.78818 0.35576 0.91427 0.12930 0.78871 0.11154 55939.179582 0.000318 0.11176 0.01687 0.98182 0 9.48570 0.45023 8.21466 0.38990 1.06013 0.15187 0.91798 0.13151 55939.180303 0.000402 0.08925 0.01334 0.97842 0 9.49473 0.40357 8.17811 0.34762 0.84738 0.12139 0.72899 0.10443 55939.181081 0.000376 0.09402 0.01395 1.00000 0 9.55540 0.41693 8.27555 0.36108 0.89835 0.12740 0.77804 0.11033 55939.181842 0.000385 0.10066 0.01497 0.97744 0 8.92703 0.40004 7.72994 0.34639 0.89859 0.12743 0.77804 0.11033 55939.182702 0.000475 0.11874 0.01407 0.99390 0 9.62026 0.37287 8.33062 0.32289 1.14234 0.12794 0.98924 0.11079 55939.183639 0.000463 0.12655 0.01551 0.95625 0 9.02058 0.36502 7.81000 0.31603 1.14158 0.13206 0.98842 0.11434 55939.184417 0.000315 0.11316 0.01732 0.99083 0 9.47590 0.45968 8.03881 0.38993 1.07227 0.15563 0.90849 0.13185 55939.185057 0.000324 0.11445 0.01751 0.97321 0 9.23502 0.44769 7.85722 0.38090 1.05691 0.15334 0.90016 0.13064 55939.185720 0.000339 0.10546 0.01647 0.96581 0 9.32735 0.43452 8.06356 0.37564 0.98364 0.14658 0.85016 0.12667
