/* ** ** 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 56055.365938 0.000535 0.18614 0.02855 0.96757 0 3.53672 0.21433 3.05512 0.18514 0.65832 0.09274 0.56776 0.07998 56055.366829 0.000356 0.11400 0.02607 0.94309 0 3.87916 0.27828 3.36201 0.24118 0.44221 0.09602 0.38322 0.08322 56055.367651 0.000466 0.18991 0.02952 0.98758 0 3.80900 0.23830 3.29939 0.20641 0.72336 0.10293 0.62658 0.08916 56055.368603 0.000486 0.17903 0.02817 0.97024 0 3.87323 0.23699 3.35729 0.20542 0.69344 0.10052 0.60124 0.08716 56055.369503 0.000414 0.21257 0.03357 1.00000 0 3.76096 0.25064 3.25995 0.21725 0.79945 0.11446 0.69290 0.09921 56055.370724 0.000807 0.16054 0.01998 0.96406 0 4.03926 0.18584 3.50049 0.16105 0.64845 0.07499 0.56203 0.06499
