/* ** ** 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 56047.183172 0.000723 13.18747 3.72426 0.98000 0 0.14575 0.03982 0.12285 0.03355 1.92201 0.13735 1.62029 0.11578 56047.184549 0.000654 15.68311 4.77806 0.97345 0 0.13521 0.04002 0.11414 0.03379 2.12045 0.15289 1.79002 0.12907 56047.185854 0.000651 16.37229 5.11085 0.95556 0 0.13214 0.04013 0.11157 0.03388 2.16351 0.15647 1.82674 0.13212 56047.187099 0.000593 23.51271 8.79836 0.98049 0 0.09869 0.03624 0.08333 0.03060 2.32058 0.16733 1.95923 0.14127 56047.188334 0.000642 14.85450 4.35023 0.96396 0 0.14680 0.04167 0.12386 0.03516 2.18058 0.15723 1.84021 0.13269 56047.189688 0.000712 11.54733 3.00381 0.97154 0 0.16970 0.04243 0.14310 0.03577 1.95960 0.14087 1.65214 0.11877 56047.191066 0.000666 18.30789 5.93469 0.96957 0 0.11579 0.03662 0.09772 0.03090 2.11993 0.15110 1.78913 0.12752 56047.192379 0.000648 19.18745 5.96797 0.94643 0 0.13094 0.03976 0.11050 0.03356 2.51242 0.16897 2.12018 0.14259
