/* ** ** 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 55365.907435 0.000350 0.14421 0.02204 0.97521 0 6.42124 0.34476 5.89927 0.31674 0.92598 0.13248 0.85071 0.12171 55365.908161 0.000376 0.13740 0.02092 0.96154 0 6.29165 0.32977 5.78022 0.30296 0.86446 0.12360 0.79419 0.11355 55365.908859 0.000321 0.17723 0.02771 0.95495 0 5.70008 0.33990 5.23674 0.31227 1.01024 0.14604 0.92812 0.13417 55365.909501 0.000321 0.15026 0.02329 1.00000 0 6.49303 0.36228 5.96522 0.33283 0.97562 0.14111 0.89631 0.12964 55365.910161 0.000339 0.15314 0.02350 0.97436 0 6.18971 0.34528 5.68656 0.31722 0.94787 0.13552 0.87082 0.12451 55365.910988 0.000489 0.10302 0.01578 0.97041 0 6.28045 0.28809 5.76993 0.26467 0.64703 0.09458 0.59443 0.08689 55365.911802 0.000324 0.15777 0.02405 0.99107 0 6.22601 0.35438 5.71991 0.32557 0.98225 0.13891 0.90240 0.12762 55365.912534 0.000408 0.13499 0.02058 1.00000 0 5.67704 0.30028 5.21557 0.27587 0.76636 0.10957 0.70407 0.10067 55365.913781 0.000839 0.17724 0.01672 0.97586 0 5.95519 0.21399 5.47111 0.19660 1.05552 0.09207 0.96972 0.08459 55365.914961 0.000341 0.14979 0.02318 0.97458 0 6.21638 0.34365 5.71106 0.31572 0.93117 0.13461 0.85548 0.12367 55365.915986 0.000683 0.11397 0.01379 0.96422 0 6.62310 0.25004 6.08473 0.22971 0.75483 0.08677 0.69347 0.07972 55365.958681 0.000440 0.11095 0.01655 0.98026 0 6.59435 0.31236 6.05921 0.28701 0.73163 0.10347 0.67226 0.09507 55365.959503 0.000382 0.13378 0.02017 0.98485 0 6.26822 0.32704 5.75955 0.30050 0.83856 0.11859 0.77051 0.10897 55365.960327 0.000443 0.11737 0.01755 0.96732 0 6.27543 0.30438 5.76617 0.27968 0.73658 0.10417 0.67680 0.09571 55365.961227 0.000457 0.10818 0.01652 0.98101 0 6.36326 0.29963 5.84688 0.27532 0.68836 0.10002 0.63250 0.09191 55365.961997 0.000312 0.16124 0.02438 0.97222 0 6.62799 0.37070 6.09012 0.34062 1.06871 0.15014 0.98199 0.13796 55365.962801 0.000492 0.10609 0.01599 0.99412 0 6.01546 0.28027 5.52730 0.25753 0.63819 0.09148 0.58640 0.08406 55365.963915 0.000622 0.12874 0.01553 0.94884 0 6.59201 0.26159 6.05706 0.24036 0.84865 0.09669 0.77978 0.08884
