/* ** ** 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 56037.096086 0.001137 7.59430 1.21199 0.97201 0 0.30840 0.04650 0.25688 0.03875 2.34206 0.12240 1.94596 0.10170 56037.436051 0.000767 9.60977 2.23170 0.95372 0 0.26242 0.05812 0.17263 0.03819 2.52176 0.17601 1.67188 0.11651 56037.767194 0.000556 20.74894 7.29869 0.97396 0 0.12070 0.04157 0.10242 0.03528 2.50440 0.17891 2.12327 0.15168 56037.768317 0.000567 9.51491 2.32032 0.98469 0 0.25685 0.05986 0.21579 0.05027 2.44390 0.17535 2.04923 0.14704 56037.769497 0.000613 8.35213 1.88443 0.97170 0 0.27301 0.05841 0.23099 0.04941 2.28024 0.16345 1.92713 0.13812 56037.770828 0.000718 9.30823 2.11355 0.95796 0 0.23768 0.05152 0.20096 0.04355 2.21237 0.14967 1.85895 0.12575 56037.838154 0.000399 10.04529 3.02965 0.97826 0 0.23350 0.06741 0.19705 0.05688 2.34556 0.20487 1.96951 0.17199
