/* ** ** 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 55017.087814 0.001118 0.30516 0.07779 0.97403 1 0.54303 0.06630 0.35119 0.04285 0.16571 0.03708 0.10667 0.02385 55017.091678 0.002745 0.12376 0.02544 0.98261 1 0.73676 0.05016 0.46611 0.03173 0.09118 0.01769 0.05773 0.01120 55017.158623 0.005955 0.14851 0.02776 0.98673 1 0.60401 0.04100 0.22168 0.01504 0.08970 0.01562 0.03263 0.00568 55017.484293 0.003820 0.19255 0.03512 0.98752 1 0.62817 0.04651 0.28863 0.02137 0.12095 0.02016 0.05545 0.00924 55017.834865 0.002092 0.11728 0.02770 0.96529 1 0.60361 0.04590 0.49220 0.03743 0.07079 0.01583 0.05755 0.01287 55017.839644 0.002687 0.15499 0.03223 0.93333 1 0.49021 0.03772 0.40116 0.03086 0.07598 0.01468 0.06232 0.01204
