/* ** ** Swift/XRT hardness ratio for SS 433. ** 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 56935.555813 0.000752 0.51382 0.14267 0.95385 0 0.41636 0.06775 0.31157 0.05070 0.21394 0.04813 0.16061 0.03614 56935.557089 0.000524 1.11553 0.36804 0.98895 0 0.27074 0.06567 0.20152 0.04888 0.30201 0.06754 0.22384 0.05005 56935.557937 0.000324 3.28153 1.55477 0.99107 0 0.14650 0.06108 0.10913 0.04549 0.48073 0.10817 0.35885 0.08074 56935.558900 0.000639 0.70047 0.20662 0.96833 0 0.35473 0.06824 0.26775 0.05151 0.24848 0.05556 0.18723 0.04187 56935.560477 0.000938 0.45946 0.12740 0.97545 0 0.36642 0.05793 0.27131 0.04289 0.16836 0.03835 0.12455 0.02838 56935.562092 0.000677 1.25362 0.43232 0.96580 0 0.19046 0.05000 0.14020 0.03681 0.23877 0.05340 0.17729 0.03964 56935.564004 0.001236 0.71091 0.16545 0.97421 0 0.30278 0.04631 0.22240 0.03401 0.21525 0.03776 0.15780 0.02768
