/* ** ** 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 58545.366526 0.000365 0.41491 0.07200 0.98413 0 2.82395 0.26845 1.92210 0.18213 1.17169 0.17011 0.79097 0.11455 58545.367227 0.000336 0.40109 0.06771 0.91379 0 3.20240 0.29061 2.34288 0.21244 1.28446 0.18283 0.94005 0.13373 58545.368167 0.000605 0.49040 0.06079 0.98086 0 2.67126 0.19281 2.00206 0.14448 1.30998 0.13201 0.98151 0.09889 58545.369105 0.000333 0.38980 0.06595 0.97391 0 3.00994 0.27159 2.26945 0.20477 1.17328 0.16790 0.88503 0.12665 58545.369863 0.000425 0.38547 0.06508 0.95238 0 2.41781 0.21659 1.83356 0.16425 0.93199 0.13337 0.70802 0.10132 58545.370615 0.000327 0.47925 0.08418 0.96460 0 2.54515 0.25847 1.91553 0.19453 1.21975 0.17482 0.91819 0.13160 58545.371249 0.000307 0.44907 0.07694 0.99057 0 2.87458 0.28042 2.15953 0.21068 1.29088 0.18181 0.96808 0.13634 58545.371958 0.000402 0.37337 0.06339 0.99281 0 2.54953 0.23293 1.92371 0.17576 0.95192 0.13622 0.71828 0.10279 58545.372724 0.000365 0.38035 0.06473 0.96032 0 2.83761 0.25751 2.14141 0.19433 1.07930 0.15538 0.81489 0.11731 58545.373480 0.000391 0.38725 0.06499 0.96296 0 2.61875 0.23312 1.97880 0.17615 1.01412 0.14427 0.76650 0.10904 58545.374241 0.000370 0.42352 0.07259 0.96094 0 2.51949 0.23771 1.90261 0.17950 1.06704 0.15270 0.80588 0.11532 58545.375051 0.000440 0.59349 0.09161 0.95395 0 2.14520 0.20048 1.61649 0.15107 1.27316 0.15641 0.95878 0.11778 58545.375797 0.000307 0.44507 0.07723 1.00000 0 2.81300 0.27596 2.10602 0.20658 1.25197 0.17920 0.93513 0.13382 58545.376593 0.000489 0.38203 0.05707 0.97041 0 2.69030 0.21344 2.00554 0.15909 1.02778 0.13010 0.76639 0.09701
