/* ** ** 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 55993.648459 0.000613 7.46573 1.57640 0.97642 0 0.29654 0.05885 0.25525 0.05064 2.21387 0.15970 1.90708 0.13756 55993.649755 0.000683 7.08543 1.47066 0.96186 0 0.28220 0.05491 0.24458 0.04759 1.99950 0.14439 1.73255 0.12511 55993.651613 0.001175 6.60082 1.04364 0.97286 0 0.30136 0.04468 0.26029 0.03858 1.98919 0.10928 1.72155 0.09458 55993.710343 0.000483 5.42559 1.96700 0.89222 0 0.38593 0.12866 0.12182 0.04061 2.09390 0.29832 0.66783 0.09511 55993.711222 0.000396 5.82282 2.21866 0.91971 0 0.44540 0.15752 0.13582 0.04802 2.59348 0.36774 0.79323 0.11244 55993.712029 0.000411 7.54535 3.26541 0.95775 0 0.30641 0.12524 0.09465 0.03864 2.31200 0.32886 0.73329 0.10418 55993.712984 0.000544 6.85373 2.77134 0.89894 0 0.28221 0.10669 0.08499 0.03212 1.93417 0.27746 0.58490 0.08388 55993.714066 0.000538 8.11893 3.70216 0.92473 0 0.22829 0.09884 0.07056 0.03057 1.85348 0.26523 0.57597 0.08241 55993.715001 0.000391 9.73603 4.57253 0.91852 0 0.25905 0.11588 0.08144 0.03642 2.52216 0.36101 0.79893 0.11431 55993.715840 0.000448 9.48926 4.45749 0.89032 0 0.24776 0.11085 0.07646 0.03420 2.35109 0.33650 0.71788 0.10271 55993.716795 0.000506 12.21946 6.35443 0.93143 0 0.16470 0.08236 0.05008 0.02504 2.01253 0.28732 0.60912 0.08695 55993.717634 0.000327 16.17192 9.98283 0.94690 0 0.18591 0.11162 0.05677 0.03409 3.00651 0.43130 0.92381 0.13249 55993.718398 0.000437 11.74709 6.12002 0.91391 0 0.19349 0.09683 0.06025 0.03013 2.27299 0.32941 0.70991 0.10277
