/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 56394.771241 0.000492 7.43094 1.59627 0.97647 0 0.44615 0.09026 0.31978 0.06471 3.31530 0.23934 2.37006 0.17107 56394.772176 0.000443 9.08053 2.13305 0.98039 0 0.42138 0.09425 0.28619 0.06399 3.82639 0.27469 2.63665 0.18919 56394.773116 0.000498 9.10586 2.13933 0.97093 0 0.37153 0.08308 0.25849 0.05780 3.38314 0.24384 2.35897 0.17002 56394.774129 0.000515 10.60641 2.77730 0.95506 0 0.31528 0.07941 0.21931 0.05524 3.34403 0.23960 2.32950 0.16690 56394.775130 0.000486 20.09766 7.11531 0.98810 0 0.17453 0.06050 0.11698 0.04049 3.50766 0.25207 2.37940 0.17098 56394.776166 0.000550 12.57531 3.50707 0.96842 0 0.24674 0.06648 0.17233 0.04644 3.10281 0.22351 2.15963 0.15558 56394.777210 0.000495 9.90637 2.41648 0.99415 0 0.33481 0.07800 0.23321 0.05433 3.31679 0.23974 2.31126 0.16707 56394.778217 0.000512 9.85482 2.40459 0.97740 0 0.33421 0.07790 0.23035 0.05367 3.29354 0.23780 2.27416 0.16415 56394.779247 0.000518 8.95262 2.16800 0.97765 0 0.36996 0.08562 0.25607 0.05926 3.31209 0.23605 2.28030 0.16249 56394.780486 0.000720 21.14473 5.99109 0.99197 0 0.16819 0.04666 0.11575 0.03210 3.55642 0.20538 2.46879 0.14256
