/* ** ** 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 58543.368067 0.000532 0.38070 0.06417 0.96739 0 2.30837 0.20641 1.44789 0.12908 0.87880 0.12555 0.55981 0.07964 58543.369179 0.000579 0.33621 0.05521 0.96500 0 2.20156 0.18370 1.54328 0.12878 0.74019 0.10468 0.51900 0.07340 58543.370272 0.000509 0.32608 0.05411 0.97727 0 2.51088 0.20715 1.75797 0.14504 0.81876 0.11787 0.57327 0.08253 58543.371456 0.000674 0.26950 0.04594 0.96996 0 2.10583 0.16625 1.47225 0.11622 0.56752 0.08573 0.39428 0.05955 58543.372636 0.000506 0.43334 0.07412 0.98286 0 1.90184 0.18059 1.34163 0.12738 0.82413 0.11724 0.57933 0.08241 58543.373626 0.000483 0.43307 0.07533 0.97006 0 1.97564 0.19040 1.39924 0.13485 0.85559 0.12390 0.60544 0.08768 58543.374581 0.000472 0.38510 0.06578 0.97546 0 2.27475 0.20600 1.60213 0.14509 0.87601 0.12686 0.61687 0.08933 58543.375527 0.000469 0.41450 0.07111 0.98148 0 2.11132 0.19694 1.49521 0.13947 0.87515 0.12599 0.62015 0.08927 58543.376444 0.000448 0.40471 0.07048 0.98710 0 2.22193 0.20881 1.56726 0.14728 0.89923 0.13183 0.63425 0.09296 58543.377202 0.000310 0.21754 0.05362 0.94393 0 2.58204 0.26762 1.82418 0.18907 0.56170 0.12560 0.39670 0.08870 58543.377856 0.000344 0.17523 0.04259 0.95798 0 2.82959 0.26954 2.01040 0.19150 0.49584 0.11088 0.35146 0.07859 58543.378655 0.000448 0.37072 0.06328 0.96129 0 2.49084 0.22160 1.76263 0.15681 0.92341 0.13452 0.65477 0.09539 58543.379480 0.000376 0.24023 0.05252 0.94615 0 2.48352 0.24000 1.76290 0.17036 0.59663 0.11701 0.42347 0.08305
