/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 54933.065846 0.037610 0.10646 0.02056 0.13348 1 0.68744 0.04146 0.32193 0.01941 0.07319 0.01343 0.03458 0.00634 54933.892413 0.001830 0.13746 0.03290 0.99206 1 0.79564 0.06717 0.45680 0.03845 0.10937 0.02449 0.06400 0.01431 54933.896233 0.001990 0.14061 0.03358 0.97080 1 0.70894 0.05950 0.42860 0.03597 0.09968 0.02229 0.06015 0.01345 54933.899284 0.001060 0.21846 0.05427 0.98630 1 0.84310 0.08918 0.50538 0.05346 0.18419 0.04140 0.11056 0.02485 54933.902247 0.001903 0.14501 0.03469 0.98473 1 0.71792 0.06100 0.42865 0.03642 0.10410 0.02328 0.06202 0.01387 54933.906590 0.002440 0.11755 0.02650 0.97212 1 0.77515 0.05678 0.46010 0.03370 0.09112 0.01943 0.05388 0.01149 54933.963516 0.001627 0.23593 0.05904 1.00000 1 0.64771 0.07268 0.30293 0.03398 0.15282 0.03418 0.07143 0.01597 54933.967264 0.002121 0.17084 0.04165 0.98630 1 0.67622 0.06334 0.32259 0.03022 0.11553 0.02600 0.05522 0.01243 54933.971723 0.002339 0.15294 0.03695 0.98137 1 0.69181 0.06075 0.33012 0.02898 0.10580 0.02381 0.05033 0.01133 54933.976255 0.002193 0.18301 0.04159 0.98581 1 0.70963 0.06413 0.33774 0.03052 0.12987 0.02708 0.06180 0.01289
