/* ** ** 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 58125.495078 0.000472 0.25802 0.00942 1.00000 0 52.96736 0.87296 46.91464 0.77315 13.66671 0.44546 12.10476 0.39450 58125.496036 0.000486 0.25489 0.00937 1.00000 0 51.54749 0.84682 45.74379 0.75136 13.13896 0.43237 11.65475 0.38347 58125.496994 0.000472 0.26366 0.00967 0.99387 0 51.84423 0.86368 46.01143 0.76649 13.66915 0.44643 12.13001 0.39617 58125.497943 0.000477 0.26728 0.00974 1.00000 0 50.49573 0.84749 44.88820 0.75335 13.49650 0.43662 12.00085 0.38824 58125.498909 0.000489 0.25704 0.00929 1.00000 0 51.25817 0.83889 45.58531 0.74599 13.17542 0.42463 11.71701 0.37765 58125.499893 0.000495 0.24621 0.00893 1.00000 0 52.72748 0.84658 46.93410 0.75353 12.98209 0.42197 11.55613 0.37563 58125.500868 0.000480 0.25937 0.00945 0.99398 0 52.02370 0.85689 46.22499 0.76135 13.49335 0.43836 11.98849 0.38948 58125.501849 0.000501 0.24792 0.00902 0.99422 0 51.95037 0.83637 46.18442 0.74352 12.87976 0.42015 11.44808 0.37350 58125.502850 0.000501 0.24163 0.00885 1.00000 0 52.96861 0.84899 46.79539 0.75000 12.79906 0.42142 11.30633 0.37221 58125.503869 0.000518 0.24483 0.00888 1.00000 0 50.49900 0.80900 44.93744 0.71988 12.36391 0.40251 11.00608 0.35832 58125.505310 0.000923 0.24979 0.00674 1.00000 0 51.00048 0.60920 45.40597 0.54237 12.73951 0.30849 11.34023 0.27459
