/* ** ** 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 57364.430933 0.000324 0.06542 0.01531 0.99107 0 6.31579 0.36062 5.77418 0.32969 0.41318 0.09379 0.37776 0.08575 57364.431842 0.000584 0.08677 0.01281 0.98515 0 6.38444 0.26924 5.79773 0.24450 0.55397 0.07835 0.50335 0.07118 57364.433048 0.000622 0.08421 0.01241 0.97209 0 6.22606 0.25753 5.69119 0.23540 0.52429 0.07415 0.47927 0.06778 57364.434264 0.000593 0.08554 0.01310 0.96585 0 6.26300 0.26235 5.72428 0.23978 0.53576 0.07895 0.48967 0.07215 57364.435404 0.000547 0.08884 0.01366 0.96825 0 6.58897 0.27979 6.02121 0.25568 0.58533 0.08650 0.53490 0.07905 57364.436584 0.000634 0.06569 0.01063 0.96347 0 6.55612 0.26244 5.99297 0.23990 0.43069 0.06754 0.39369 0.06174 57364.437637 0.000420 0.06174 0.01292 0.97241 0 6.64575 0.32570 6.07418 0.29769 0.41031 0.08350 0.37504 0.07632 57364.438398 0.000341 0.05922 0.01363 0.97458 0 6.43785 0.35225 5.88306 0.32190 0.38126 0.08525 0.34841 0.07791 57364.439310 0.000570 0.08694 0.01304 0.97462 0 6.55327 0.27773 5.99165 0.25393 0.56976 0.08194 0.52098 0.07493 57364.440485 0.000605 0.08499 0.01286 0.98565 0 6.12580 0.25763 5.59884 0.23547 0.52065 0.07567 0.47585 0.06916 57364.441717 0.000628 0.11257 0.01415 0.98157 0 6.57441 0.26195 6.00984 0.23945 0.74008 0.08825 0.67653 0.08067
