/* ** ** 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 58164.426889 0.000567 0.38120 0.06346 0.96429 0 1.68073 0.14763 1.38916 0.12201 0.64070 0.09061 0.52998 0.07495 58164.428032 0.000576 0.36790 0.06228 0.99497 0 1.65200 0.14475 1.34808 0.11812 0.60777 0.08802 0.49536 0.07174 58164.429187 0.000579 0.38064 0.06376 0.97000 0 1.64824 0.14798 1.35546 0.12169 0.62739 0.08873 0.51632 0.07302 58164.430425 0.000660 0.32361 0.05420 0.96053 0 1.69250 0.13993 1.37590 0.11374 0.54771 0.07978 0.44548 0.06490 58164.431481 0.000396 0.58077 0.10464 0.98540 0 1.57252 0.17552 1.27538 0.14238 0.91328 0.12917 0.74198 0.10493 58164.432390 0.000512 0.42996 0.07349 0.97175 0 1.65427 0.15460 1.34061 0.12528 0.71127 0.10179 0.57630 0.08247 58164.433423 0.000521 0.39720 0.06778 0.95556 0 1.77452 0.16264 1.43956 0.13193 0.70483 0.10146 0.57327 0.08253 58164.434592 0.000648 0.30774 0.05060 0.95089 0 1.87548 0.14832 1.51734 0.12000 0.57716 0.08320 0.46744 0.06739 58164.435697 0.000457 0.40190 0.06891 0.96835 0 1.97852 0.18420 1.59615 0.14861 0.79516 0.11448 0.64446 0.09277 58164.436817 0.000663 0.40349 0.06075 0.96070 0 1.77353 0.14617 1.42168 0.11718 0.71561 0.09016 0.57368 0.07228
