/* ** ** 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 58350.025047 0.000301 0.16504 0.02584 0.98077 0 6.96188 0.40708 5.82207 0.34046 1.14897 0.16688 0.96168 0.13962 58350.026401 0.001053 0.18470 0.01522 0.97038 0 6.59122 0.21471 5.48399 0.17862 1.21737 0.09214 1.01188 0.07659 58350.028035 0.000566 0.16449 0.04086 1.00000 1 5.92420 0.54728 1.21177 0.11194 0.97445 0.22471 0.19930 0.04596 58350.028994 0.000392 0.29540 0.07344 0.96296 1 5.36114 0.63855 1.09677 0.13064 1.58370 0.34561 0.32308 0.07050 58350.029953 0.000566 0.14283 0.03429 0.89744 1 7.72950 0.63981 1.59545 0.13205 1.10397 0.24875 0.22695 0.05114 58350.030955 0.000436 0.18690 0.04461 1.00000 1 7.32234 0.70735 1.49169 0.14408 1.36853 0.29869 0.28000 0.06110 58350.031841 0.000450 0.23015 0.05718 0.96774 1 5.64234 0.61100 1.15628 0.12521 1.29857 0.29039 0.26667 0.05963 58350.032872 0.000581 0.18927 0.04561 0.95000 1 5.57876 0.52965 1.15466 0.10961 1.05588 0.23387 0.21806 0.04828 58350.034020 0.000566 0.17452 0.04222 0.94872 1 6.06030 0.55899 1.25120 0.11539 1.05763 0.23655 0.21622 0.04835 58350.035342 0.000755 0.18081 0.03663 0.94235 1 6.33700 0.49813 1.30405 0.10249 1.14581 0.21394 0.23557 0.04397
