/* ** ** 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 56365.459283 0.000385 0.50938 0.08904 0.94737 0 2.96480 0.29761 1.54438 0.15503 1.51022 0.21612 0.78668 0.11258 56365.460073 0.000405 0.50304 0.08822 0.97143 0 2.79610 0.28675 1.45651 0.14937 1.40655 0.20009 0.73268 0.10423 56365.460875 0.000396 0.51559 0.09066 0.97810 0 2.79538 0.28795 1.45613 0.15000 1.44128 0.20537 0.75077 0.10698 56365.461801 0.000530 0.39642 0.06593 0.96721 0 2.82161 0.25218 1.46979 0.13136 1.11853 0.15689 0.58265 0.08172 56365.462825 0.000495 0.37186 0.06301 0.97661 0 3.04804 0.27242 1.58774 0.14191 1.13344 0.16317 0.59042 0.08500 56365.463959 0.000639 0.43460 0.06221 0.96024 0 2.93893 0.23085 1.53091 0.12025 1.27727 0.15285 0.66533 0.07962 56365.857858 0.000330 0.46091 0.07988 0.97368 0 2.20768 0.21302 1.92710 0.18595 1.01754 0.14650 0.88822 0.12788 56365.858492 0.000304 0.45984 0.07895 0.98095 0 2.41008 0.23166 2.10378 0.20222 1.10825 0.15766 0.96740 0.13763 56365.859140 0.000344 0.38883 0.06570 0.99160 0 2.47482 0.22234 2.16029 0.19408 0.96227 0.13772 0.83998 0.12021 56365.859805 0.000321 0.37470 0.06227 0.98198 0 2.80957 0.24526 2.45249 0.21409 1.05276 0.14888 0.91896 0.12996 56365.860459 0.000333 0.47418 0.08255 0.97391 0 2.13804 0.21188 1.86631 0.18496 1.01382 0.14509 0.88498 0.12665 56365.861107 0.000315 0.37268 0.06110 0.97248 0 2.96287 0.25270 2.58631 0.22058 1.10420 0.15462 0.96387 0.13497 56365.861756 0.000333 0.43838 0.07622 0.98261 0 2.26793 0.21817 1.97970 0.19044 0.99421 0.14401 0.86786 0.12570 56365.862479 0.000391 0.44523 0.06643 0.98519 0 2.54779 0.21271 2.22398 0.18567 1.13436 0.14026 0.99019 0.12243 56365.863197 0.000327 0.41483 0.07066 1.00000 0 2.42235 0.22373 2.11449 0.19529 1.00485 0.14381 0.87714 0.12553 56365.863891 0.000367 0.35545 0.05939 0.97638 0 2.56259 0.21731 2.23690 0.18969 0.91086 0.13114 0.79510 0.11447 56365.864643 0.000379 0.36994 0.06168 0.96947 0 2.41681 0.20675 2.10965 0.18048 0.89408 0.12796 0.78045 0.11169 56365.866162 0.001140 0.43480 0.03709 0.96701 0 2.74536 0.12790 2.39645 0.11164 1.19369 0.08529 1.04198 0.07445 56365.867653 0.000350 0.36274 0.06120 0.96694 0 2.64715 0.22898 2.31072 0.19988 0.96022 0.13908 0.83819 0.12141 56365.868373 0.000370 0.42998 0.06903 0.98438 0 2.38131 0.20853 2.07867 0.18203 1.02391 0.13776 0.89378 0.12025
