/* ** ** 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 58303.570576 0.000055 0.05125 0.05267 0.99594 0 2.55196 0.60407 2.06549 0.48892 0.13079 0.13079 0.10586 0.10586 58303.572480 0.001830 0.11366 0.02685 0.99206 1 2.40478 0.18312 0.56354 0.04291 0.27332 0.06112 0.06400 0.01431 58303.575385 0.001075 0.18897 0.04622 1.00000 1 2.42894 0.24066 0.57224 0.05669 0.45899 0.10264 0.10811 0.02417 58303.577811 0.001351 0.19335 0.04355 0.99661 1 2.26284 0.20913 0.53141 0.04911 0.43753 0.08988 0.10296 0.02115 58303.653374 0.000260 0.19942 0.05477 0.94839 0 2.16713 0.24643 1.88303 0.21413 0.43216 0.10804 0.37551 0.09388 58303.655175 0.001525 0.15011 0.03597 0.95238 1 2.12004 0.18245 0.53161 0.04574 0.31825 0.07116 0.08000 0.01789 58303.658197 0.001496 0.25227 0.05335 0.96363 1 1.78358 0.16925 0.44624 0.04234 0.44994 0.08503 0.11284 0.02133
