/* ** ** Swift/XRT hardness ratio for 4U 1608-52. ** 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 54298.595391 0.000683 2.58695 0.35734 1.00000 1 2.75308 0.32738 0.67301 0.08000 7.12209 0.50058 1.73458 0.12191 54298.596785 0.000712 2.25349 0.29911 1.00000 1 2.94671 0.32904 0.71495 0.07982 6.64040 0.47647 1.61085 0.11556 54298.598238 0.000741 2.32875 0.31051 1.00000 1 2.78695 0.31389 0.67417 0.07593 6.49010 0.46321 1.56771 0.11188 54298.599661 0.000683 2.08156 0.27216 0.95745 1 3.50638 0.38338 0.84368 0.09223 7.29875 0.52329 1.75535 0.12583 54298.601114 0.000770 2.17862 0.28388 1.00000 1 2.81108 0.30523 0.68143 0.07399 6.12428 0.44115 1.48367 0.10687 54298.602566 0.000683 2.30803 0.31598 1.00000 1 3.03756 0.35443 0.73222 0.08543 7.01078 0.50205 1.69136 0.12110 54298.604266 0.001017 1.84476 0.19300 0.99441 1 3.66552 0.31498 0.89086 0.07654 6.76201 0.40356 1.64173 0.09797 54298.659955 0.000784 2.89872 0.43522 1.00000 1 2.29630 0.30325 0.51081 0.06746 6.65633 0.47549 1.47945 0.10566 54298.661465 0.000726 2.53285 0.35729 0.98000 1 2.91985 0.35395 0.63246 0.07667 7.39555 0.53352 1.60244 0.11560 54298.663295 0.001104 2.39695 0.26900 0.98724 1 3.03866 0.29084 0.66262 0.06342 7.28351 0.42679 1.58575 0.09292
