/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 55347.450890 0.000388 0.15382 0.03605 0.97761 0 2.40746 0.20573 2.08082 0.17782 0.37032 0.08081 0.32115 0.07008 55347.451781 0.000503 0.10045 0.02390 0.95977 0 2.74815 0.19585 2.36112 0.16826 0.27604 0.06266 0.23681 0.05374 55347.452600 0.000315 0.17082 0.04090 0.97248 0 2.66205 0.24351 2.29519 0.20995 0.45473 0.10063 0.39198 0.08675 55347.453726 0.000810 0.06998 0.01620 0.98571 0 2.40271 0.14454 2.07724 0.12496 0.16814 0.03760 0.14517 0.03246 55347.454955 0.000420 0.10576 0.02523 0.97931 0 3.03430 0.22304 2.63399 0.19361 0.32092 0.07283 0.27850 0.06320 55347.455838 0.000463 0.10736 0.02528 0.96875 0 2.77852 0.20536 2.40273 0.17758 0.29831 0.06670 0.25849 0.05780 55347.456833 0.000532 0.10438 0.02455 0.96196 0 2.51066 0.18267 2.16386 0.15743 0.26207 0.05860 0.22637 0.05062 55347.457765 0.000399 0.12478 0.03045 0.97826 0 2.66748 0.21519 2.31672 0.18689 0.33286 0.07667 0.28909 0.06659 55347.458778 0.000613 0.08359 0.01947 0.98113 0 2.67292 0.17441 2.30659 0.15049 0.22342 0.04996 0.19263 0.04307 55347.459834 0.000443 0.11702 0.02768 0.96078 0 2.68171 0.20669 2.32936 0.17953 0.31380 0.07017 0.27256 0.06095 55347.461029 0.000752 0.10881 0.02013 0.98077 0 2.72703 0.15804 2.36208 0.13689 0.29674 0.05212 0.25722 0.04518
