/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 56986.620587 0.000508 0.54259 0.14750 1.00000 1 2.08023 0.33715 0.44082 0.07143 1.12871 0.24633 0.24000 0.05237 56986.621545 0.000450 0.81957 0.24497 1.00000 1 1.54964 0.31381 0.32952 0.06672 1.27004 0.27922 0.26913 0.05916 56986.622649 0.000654 0.35435 0.09240 0.93333 1 2.52046 0.33071 0.53247 0.06987 0.89311 0.20126 0.18912 0.04261 56986.623710 0.000407 0.62546 0.17831 0.96429 1 2.24200 0.39637 0.47408 0.08381 1.40228 0.31360 0.29630 0.06625 56986.625249 0.001133 0.43940 0.09295 0.93290 1 1.88179 0.21616 0.39824 0.04575 0.82685 0.14688 0.17512 0.03111 56986.956940 0.000755 0.51058 0.13747 0.92308 1 1.53375 0.23841 0.34054 0.05293 0.78310 0.17216 0.17382 0.03821 56986.958480 0.000784 0.35671 0.09336 0.96296 1 1.94962 0.25963 0.42805 0.05700 0.69544 0.15669 0.15276 0.03442 56986.960020 0.000755 0.46990 0.12441 1.00000 1 1.63107 0.25264 0.35624 0.05517 0.76644 0.16458 0.16814 0.03610 56986.961531 0.000755 0.51455 0.13952 1.00000 1 1.41361 0.22436 0.31261 0.04962 0.72737 0.15991 0.16045 0.03527 56986.962940 0.000625 0.35567 0.09398 1.00000 1 2.35748 0.32538 0.51991 0.07176 0.83849 0.18894 0.18473 0.04162 56986.964436 0.000872 0.37437 0.09856 1.00000 1 1.60206 0.22261 0.35547 0.04939 0.59976 0.13411 0.13333 0.02981 56986.966062 0.000755 0.44324 0.11806 1.00000 1 1.61606 0.24311 0.36119 0.05433 0.71631 0.15744 0.16045 0.03527 56986.967428 0.000610 0.48874 0.13528 0.95238 1 1.83373 0.29481 0.40904 0.06575 0.89621 0.20193 0.19858 0.04474 56986.968633 0.000596 0.42203 0.11375 0.97561 1 2.10998 0.31213 0.47034 0.06958 0.89047 0.20064 0.19858 0.04474 56986.969796 0.000566 0.48171 0.13262 0.97436 1 1.94352 0.30731 0.43244 0.06837 0.93622 0.21099 0.20903 0.04710 56986.971277 0.000915 0.34344 0.08027 0.96297 1 2.12632 0.25273 0.47622 0.05660 0.73027 0.14697 0.16390 0.03298
