/* ** ** 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 56939.009782 0.000475 1.22666 0.41481 0.96341 0 0.27948 0.07089 0.20528 0.05207 0.34283 0.07666 0.25359 0.05670 56939.010564 0.000301 0.85410 0.26782 0.97115 0 0.54868 0.11703 0.46393 0.09891 0.46862 0.10772 0.38719 0.08896 56939.011232 0.000367 0.61600 0.18052 0.97638 0 0.61506 0.11651 0.51955 0.09837 0.37887 0.08472 0.32312 0.07225 56939.011984 0.000385 1.26250 0.38767 0.94737 0 0.36776 0.08569 0.31483 0.07336 0.46430 0.09286 0.39749 0.07950 56939.012699 0.000330 1.98574 0.79835 0.98246 0 0.23458 0.07829 0.17505 0.05835 0.46582 0.10442 0.35774 0.07999 56939.013500 0.000472 0.87853 0.27690 0.98160 0 0.38243 0.08392 0.28277 0.06205 0.33597 0.07602 0.24767 0.05603 56939.014290 0.000318 1.63819 0.59403 0.96364 0 0.32308 0.09327 0.24040 0.06940 0.52927 0.11614 0.39481 0.08663 56939.014982 0.000373 1.73794 0.65245 0.94574 0 0.25640 0.07731 0.18835 0.05679 0.44561 0.09966 0.32842 0.07344 56939.015838 0.000483 1.11892 0.37153 0.96407 0 0.30200 0.07377 0.22261 0.05436 0.33791 0.07600 0.24750 0.05566 56939.016654 0.000333 1.31979 0.46105 0.99130 0 0.36575 0.09776 0.26212 0.07005 0.48272 0.10858 0.34953 0.07861 56939.017534 0.000547 1.33298 0.29301 0.95238 0 0.48931 0.08167 0.41105 0.06856 0.65224 0.09329 0.55117 0.07879 56939.018529 0.000448 1.30246 0.45220 0.95484 0 0.27304 0.07217 0.20409 0.05395 0.35562 0.08005 0.26923 0.06055 56939.019551 0.000573 1.81419 0.51656 0.97980 0 0.28122 0.06492 0.20456 0.04722 0.51019 0.08505 0.37175 0.06196
