/* ** ** 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 56383.960965 0.000518 0.23606 0.00842 1.00000 0 51.26918 0.79532 47.17521 0.73173 12.10262 0.38865 11.13659 0.35759 56383.961998 0.000515 0.23210 0.00826 0.99438 0 51.84917 0.80095 48.37679 0.74731 12.03425 0.38588 11.22831 0.36004 56383.963034 0.000521 0.23104 0.00817 1.00000 0 51.57977 0.79002 48.12590 0.73712 11.91694 0.38001 11.11896 0.35457 56383.964078 0.000524 0.22987 0.00817 1.00000 0 51.24811 0.78871 47.81508 0.73587 11.78036 0.37718 10.99118 0.35191 56383.965106 0.000503 0.24046 0.00865 1.00000 0 50.60420 0.80000 47.21384 0.74640 12.16831 0.39331 11.35311 0.36696 56383.966121 0.000512 0.23650 0.00849 1.00000 0 50.63198 0.79138 47.23941 0.73835 11.97455 0.38684 11.17200 0.36092 56383.967157 0.000524 0.23718 0.00844 1.00000 0 49.76672 0.77377 46.43388 0.72195 11.80380 0.37754 11.01332 0.35226 56383.968196 0.000515 0.23835 0.00852 1.00000 0 50.30815 0.78846 46.93914 0.73565 11.99090 0.38522 11.18790 0.35942 56383.969229 0.000518 0.23720 0.00843 1.00000 0 50.21719 0.78236 46.85455 0.72998 11.91143 0.38025 11.11382 0.35479 56383.970291 0.000544 0.22660 0.00802 1.00000 0 50.19997 0.76435 46.83897 0.71318 11.37551 0.36366 10.61390 0.33931 56383.971509 0.000674 0.25169 0.00769 1.00000 0 50.19954 0.68620 46.83822 0.64026 12.63456 0.34514 11.78856 0.32203
