/* ** ** 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 60058.411840 0.000523 0.38923 0.10118 1.00000 1 1.39747 0.19436 0.59288 0.08243 0.54394 0.11945 0.23196 0.05094 60058.412988 0.000625 0.34847 0.09280 0.97674 1 1.23688 0.16997 0.53506 0.07353 0.43102 0.09832 0.18695 0.04264 60058.414033 0.000421 0.68250 0.19495 0.96552 1 1.02085 0.18649 0.43580 0.07962 0.69673 0.15300 0.29824 0.06549 60058.414963 0.000508 0.46345 0.12613 0.94286 1 1.21453 0.18580 0.51972 0.07950 0.56287 0.12670 0.24093 0.05423 60058.416053 0.000581 0.39712 0.10697 1.00000 1 1.17539 0.17389 0.50144 0.07418 0.46677 0.10507 0.19877 0.04474 60058.416982 0.000349 0.56314 0.16250 1.00000 1 1.35810 0.24010 0.58182 0.10285 0.76480 0.17442 0.32716 0.07462 60058.417723 0.000392 0.65841 0.19278 0.96296 1 1.08793 0.20561 0.46667 0.08819 0.71631 0.16018 0.30769 0.06880 60058.418769 0.000625 0.50490 0.12186 0.92996 1 1.20005 0.16534 0.50841 0.07004 0.60590 0.12007 0.25761 0.05104
