/* ** ** 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 58578.974823 0.000098 0.09815 0.05181 0.93676 0 4.70218 0.75988 2.55132 0.40935 0.46154 0.23194 0.25157 0.12579 58578.975696 0.000755 0.20354 0.05015 0.96154 1 3.80552 0.37898 0.78465 0.07812 0.77459 0.17456 0.15886 0.03580 58578.977540 0.001089 0.14906 0.03586 0.98667 1 3.49222 0.30947 0.72841 0.06454 0.52056 0.11641 0.10811 0.02417 58578.979676 0.001046 0.17462 0.04164 0.97222 1 3.28829 0.30394 0.68086 0.06293 0.57420 0.12622 0.11919 0.02620 58578.981535 0.000813 0.18109 0.04410 0.98214 1 3.89537 0.37560 0.80639 0.07775 0.70542 0.15775 0.14546 0.03252 58578.984237 0.001888 0.17964 0.03193 0.94927 1 3.31044 0.23025 0.67970 0.04727 0.59469 0.09726 0.12225 0.01999
