/* ** ** 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 56366.253700 0.000480 0.14985 0.01144 0.98795 0 17.97171 0.49432 16.27886 0.44771 2.69309 0.19176 2.43820 0.17361 56366.254635 0.000454 0.16637 0.01273 0.98726 0 17.12878 0.49485 15.55536 0.44935 2.84977 0.20197 2.58882 0.18346 56366.255552 0.000463 0.15721 0.01207 1.00000 0 17.30093 0.49014 15.81751 0.44811 2.71985 0.19415 2.48664 0.17750 56366.256461 0.000446 0.15828 0.01216 0.99351 0 18.29411 0.51939 16.44434 0.46687 2.89556 0.20674 2.60040 0.18563 56366.257427 0.000521 0.14062 0.01086 0.97778 0 17.61707 0.47126 15.93262 0.42614 2.47735 0.17941 2.23667 0.16196 56366.258437 0.000489 0.14924 0.01134 0.99408 0 17.52842 0.48172 16.01233 0.44006 2.61595 0.18539 2.38850 0.16927 56366.259331 0.000405 0.18231 0.01435 1.00000 0 16.93313 0.52297 15.41266 0.47601 3.08711 0.22358 2.81181 0.20360 56366.260217 0.000480 0.15046 0.01154 0.98795 0 17.77473 0.49010 16.12743 0.44468 2.67440 0.19135 2.42965 0.17382 56366.261128 0.000431 0.16735 0.01308 1.00000 0 17.26877 0.50849 15.78706 0.46486 2.88990 0.20926 2.64197 0.19131 56366.262361 0.000802 0.16684 0.00958 0.98556 0 17.48504 0.37590 15.95188 0.34294 2.91716 0.15523 2.65936 0.14152
