/* ** ** 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 57514.803071 0.000049 0.18872 0.12006 0.98604 0 2.36145 0.63113 1.89921 0.50759 0.44565 0.25730 0.35842 0.20693 57514.804605 0.001467 0.19405 0.04765 0.99010 1 1.89164 0.19183 0.41130 0.04171 0.36708 0.08209 0.08000 0.01789 57514.808934 0.002862 0.17631 0.03444 0.99330 1 1.66732 0.12795 0.36061 0.02767 0.29397 0.05280 0.06337 0.01138 57514.869150 0.001598 0.11667 0.02775 0.98182 1 1.76712 0.13550 0.63386 0.04859 0.20616 0.04642 0.07362 0.01657 57514.872157 0.001409 0.13050 0.03110 0.98969 1 1.78390 0.14672 0.63413 0.05214 0.23280 0.05208 0.08333 0.01863 57514.874946 0.001380 0.15398 0.03710 0.98947 1 1.58026 0.14146 0.55394 0.04956 0.24334 0.05444 0.08511 0.01903 57514.877734 0.001409 0.15737 0.03469 0.96940 1 1.85585 0.15399 0.64517 0.05350 0.29205 0.05964 0.10209 0.02084
