/* ** ** Swift/XRT hardness ratio for PKS 2144+092. ** 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 54949.120185 0.069396 0.56860 0.14974 0.18755 1 0.02528 0.00407 0.01734 0.00278 0.01438 0.00300 0.01027 0.00214 54949.314401 0.075758 0.62434 0.15335 0.21030 1 0.02183 0.00333 0.01577 0.00241 0.01363 0.00262 0.00985 0.00190 54949.681941 0.109028 0.68137 0.15906 0.15451 1 0.02169 0.00323 0.01557 0.00232 0.01478 0.00265 0.01069 0.00192 55019.431365 0.168603 0.56552 0.15871 0.08537 1 0.02493 0.00417 0.01546 0.00251 0.01410 0.00318 0.00848 0.00185 55883.874480 0.247031 0.60753 0.13843 0.04640 1 0.03630 0.00509 0.02600 0.00364 0.02206 0.00396 0.01571 0.00282 55884.734891 0.172720 0.54163 0.11073 0.11403 1 0.02909 0.00353 0.02008 0.00244 0.01576 0.00259 0.01092 0.00179
