/* ** ** Swift/XRT hardness ratio for 4U 1608-52. ** 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 53927.881925 0.000729 2.41636 0.11942 0.99675 0 6.31742 0.26405 5.00350 0.20889 15.26513 0.40257 12.11717 0.31931 53927.904393 0.000385 2.70453 0.16934 1.00000 0 6.05281 0.32595 5.56504 0.29966 16.37000 0.52296 15.04606 0.48064 53927.905189 0.000411 2.50440 0.15344 1.00000 0 6.06553 0.31545 5.54712 0.28850 15.19054 0.49202 13.88931 0.44984 53927.905999 0.000399 2.46682 0.14995 1.00000 0 6.39313 0.32876 5.81501 0.29901 15.77072 0.51119 14.35433 0.46531 53927.906806 0.000408 2.40921 0.14537 1.00000 0 6.42293 0.32821 5.85062 0.29900 15.47419 0.49658 14.10032 0.45250 53927.907594 0.000379 2.39037 0.14308 1.00000 0 6.93960 0.35035 6.31267 0.31868 16.58821 0.53346 15.09624 0.48546 53927.908363 0.000391 2.69530 0.16855 1.00000 0 6.02273 0.32273 5.42874 0.29088 16.23306 0.52335 14.63085 0.47170 53927.909147 0.000394 2.68148 0.16982 1.00000 0 5.98871 0.32602 5.39746 0.29382 16.05858 0.51960 14.47584 0.46838 53927.910209 0.000668 2.43394 0.11563 0.99867 0 6.38078 0.25696 5.73631 0.23098 15.53044 0.39145 13.96407 0.35197 53927.948670 0.000553 2.59784 0.16923 1.00000 0 6.50138 0.36430 3.89510 0.21738 16.88958 0.56106 10.23991 0.33655 53927.949969 0.000747 2.50161 0.13356 0.99615 0 6.31256 0.28751 4.21530 0.19191 15.79157 0.43986 10.52884 0.29318 53927.973743 0.000278 2.45535 0.18248 1.00000 0 6.36201 0.40309 5.73724 0.36339 15.62098 0.60673 14.11054 0.54798
