/* ** ** 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 58221.766625 0.000694 0.09386 0.02197 0.97917 0 2.10941 0.14594 1.81888 0.12584 0.19799 0.04427 0.17050 0.03812 58221.767892 0.000567 0.11476 0.02714 0.98469 0 2.08826 0.16060 1.80991 0.13919 0.23965 0.05359 0.20760 0.04642 58221.768859 0.000399 0.14499 0.03475 0.98551 0 2.34547 0.20221 2.03191 0.17518 0.34007 0.07604 0.29461 0.06588 58221.769923 0.000666 0.10548 0.02479 0.96087 0 2.00053 0.14464 1.72169 0.12448 0.21101 0.04719 0.18130 0.04054 58221.771101 0.000512 0.13447 0.03200 0.95480 0 2.04962 0.16696 1.76265 0.14358 0.27561 0.06163 0.23708 0.05301 58221.772206 0.000593 0.09024 0.02109 0.97561 0 2.57546 0.17448 2.22228 0.15054 0.23242 0.05197 0.20033 0.04480 58221.773338 0.000538 0.11524 0.02727 0.98387 0 2.20052 0.17014 1.90324 0.14715 0.25359 0.05671 0.21894 0.04896 58221.774567 0.000692 0.08425 0.01962 0.96653 0 2.37680 0.15476 2.05732 0.13396 0.20024 0.04477 0.17345 0.03878 58221.775745 0.000486 0.12764 0.03032 0.96429 0 2.24971 0.18006 1.94010 0.15528 0.28715 0.06421 0.24733 0.05530 58221.776677 0.000446 0.13939 0.03336 0.95455 0 2.25567 0.19236 1.95535 0.16675 0.31442 0.07031 0.27256 0.06095 58221.777666 0.000544 0.12991 0.03088 0.96277 0 1.96812 0.15883 1.70516 0.13761 0.25568 0.05717 0.22136 0.04950 58221.778775 0.000564 0.10815 0.02544 0.95897 0 2.31095 0.16865 1.97665 0.14425 0.24994 0.05589 0.21426 0.04791 58221.779811 0.000472 0.12262 0.02907 0.97546 0 2.37142 0.18649 2.05461 0.16157 0.29079 0.06502 0.25199 0.05635 58221.780771 0.000489 0.12997 0.03094 0.97633 0 2.16980 0.17711 1.86680 0.15237 0.28202 0.06306 0.24283 0.05430 58221.781952 0.000692 0.10631 0.02292 0.97908 0 2.27237 0.15092 1.96976 0.13082 0.24158 0.04954 0.20937 0.04293
