/* ** ** 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 56739.203786 0.000451 1.31818 0.06536 1.00000 0 11.54425 0.43489 9.58879 0.36126 15.21736 0.49057 12.64351 0.40759 56739.204694 0.000457 1.18447 0.05728 1.00000 0 12.59355 0.45421 10.53992 0.38017 14.91662 0.48061 12.49614 0.40263 56739.205626 0.000475 1.16919 0.05628 1.00000 0 12.20542 0.43585 10.28912 0.36742 14.27046 0.46059 12.03000 0.38828 56739.206587 0.000486 1.23454 0.06006 1.00000 0 11.41082 0.41599 9.53300 0.34755 14.08707 0.45375 11.76928 0.37910 56739.207567 0.000495 1.16682 0.05607 1.00000 0 11.86729 0.42256 9.88091 0.35183 13.84695 0.44680 11.53260 0.37214 56739.208560 0.000498 1.17348 0.05653 1.00000 0 11.66795 0.41744 9.80339 0.35071 13.69214 0.44169 11.50359 0.37108 56739.209541 0.000483 1.16313 0.05583 1.00000 0 12.23344 0.43498 10.14958 0.36086 14.22905 0.45873 11.81070 0.38074 56739.210499 0.000475 1.26817 0.06259 1.00000 0 11.31171 0.42184 9.47276 0.35331 14.34519 0.46383 12.02104 0.38867 56739.211456 0.000483 1.23109 0.06048 1.00000 0 11.51059 0.42563 9.61745 0.35557 14.17060 0.45836 11.83734 0.38288 56739.212440 0.000501 1.18058 0.05714 1.00000 0 11.52865 0.41559 9.67177 0.34865 13.61047 0.43951 11.41394 0.36857 56739.213444 0.000503 1.26632 0.06242 0.99425 0 10.67376 0.39589 8.96536 0.33248 13.51641 0.43881 11.34573 0.36833 56739.214437 0.000489 1.23986 0.06057 1.00000 0 11.36300 0.41901 9.48205 0.34968 14.08854 0.45145 11.74760 0.37642 56739.215420 0.000495 1.23712 0.06078 1.00000 0 11.16196 0.41215 9.29870 0.34335 13.80865 0.44746 11.50863 0.37294 56739.216329 0.000414 1.21181 0.05860 1.00000 0 13.55049 0.48810 11.40135 0.41068 16.42057 0.52983 13.81657 0.44582 56739.217229 0.000486 1.20398 0.05773 0.99405 0 11.88532 0.42475 9.93206 0.35492 14.30968 0.45749 11.95333 0.38212 56739.218198 0.000483 1.19294 0.05775 1.00000 0 11.79539 0.42259 9.84441 0.35268 14.07125 0.45816 11.74775 0.38250 56739.219150 0.000469 1.23857 0.06100 1.00000 0 11.78796 0.43666 9.79510 0.36287 14.60025 0.47385 12.13371 0.39379 56739.220131 0.000512 1.13571 0.05414 1.00000 0 11.77737 0.41285 9.82862 0.34457 13.37563 0.43218 11.16555 0.36071 56739.221439 0.000796 1.23433 0.04782 1.00000 0 11.23821 0.32615 9.22916 0.26783 13.87164 0.35602 11.39005 0.29231
