/* ** ** 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 56047.384046 0.000310 0.47382 0.08464 0.98131 0 4.05372 0.41261 2.02252 0.20156 1.92072 0.28195 0.94412 0.13509 56047.384668 0.000312 0.41233 0.07099 0.99074 0 3.94513 0.37246 2.23547 0.21086 1.62668 0.23421 0.92164 0.13265 56047.385348 0.000367 0.38561 0.06523 0.98425 0 3.99670 0.36042 2.05577 0.18539 1.54118 0.22056 0.79306 0.11348 56047.386077 0.000362 0.47727 0.08299 0.97600 0 3.26754 0.32669 1.71410 0.17139 1.55951 0.22187 0.81680 0.11619 56047.386807 0.000367 0.42025 0.07168 0.96063 0 3.71793 0.34964 1.93110 0.18158 1.56246 0.22233 0.81680 0.11619 56047.387501 0.000327 0.48898 0.08573 0.95575 0 3.62091 0.37107 1.89582 0.19423 1.77056 0.25189 0.92268 0.13125 56047.388560 0.000732 0.46677 0.05205 0.96838 0 4.04640 0.25567 2.09617 0.13240 1.88874 0.17354 0.98491 0.09046 56047.389619 0.000327 0.49217 0.08494 0.95575 0 3.81905 0.38031 1.89661 0.18875 1.87961 0.26492 0.94123 0.13256 56047.390250 0.000304 0.50403 0.08930 0.97143 0 3.77473 0.38967 1.91758 0.19795 1.90259 0.27393 0.96682 0.13916 56047.390895 0.000341 0.37439 0.06258 0.97458 0 4.31135 0.37843 2.31127 0.20285 1.61413 0.22961 0.86652 0.12326 56047.391537 0.000301 0.49081 0.08599 0.97115 0 3.73041 0.37716 1.99289 0.20148 1.83092 0.26199 0.98151 0.14044 56047.392145 0.000307 0.54558 0.09620 0.97170 0 3.35555 0.35326 1.77432 0.18676 1.83070 0.25894 0.97249 0.13753 56047.392753 0.000301 0.53164 0.09504 0.99038 0 3.45908 0.37434 1.81611 0.19651 1.83898 0.26165 0.96747 0.13762 56047.393407 0.000353 0.45124 0.07217 0.95902 0 4.09281 0.36108 2.17781 0.19210 1.84684 0.24636 0.97985 0.13063 56047.394098 0.000339 0.46001 0.08124 0.97436 0 3.46519 0.34587 1.85777 0.18541 1.59402 0.23226 0.85597 0.12467 56047.394784 0.000347 0.45222 0.07870 0.96667 0 3.53348 0.34459 1.88323 0.18356 1.59792 0.23031 0.85849 0.12374
