/* ** ** 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 56123.245316 0.000723 9.47842 2.31904 0.96800 0 0.20185 0.04725 0.17492 0.04094 1.91318 0.13616 1.65084 0.11749 56123.246716 0.000677 14.11562 4.13261 0.98291 0 0.14128 0.04009 0.12150 0.03449 1.99427 0.14359 1.71449 0.12344 56123.247995 0.000602 12.35893 3.31202 0.95192 0 0.18808 0.04856 0.16243 0.04194 2.32443 0.16668 2.00436 0.14372 56123.249222 0.000625 9.68566 2.36226 0.98148 0 0.22344 0.05209 0.19348 0.04509 2.16414 0.15495 1.87449 0.13420 56123.250489 0.000631 7.47362 1.62474 0.98165 0 0.28419 0.05823 0.24392 0.04997 2.12394 0.15433 1.82788 0.13280 56123.251751 0.000631 11.21430 2.93102 0.96789 0 0.19378 0.04869 0.16752 0.04210 2.17309 0.15645 1.86888 0.13455 56123.253600 0.001218 10.41679 1.94004 0.96437 0 0.19600 0.03497 0.16909 0.03017 2.04170 0.10895 1.76516 0.09419
