/* ** ** 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 59316.545807 0.000330 0.27210 0.06592 0.97368 0 1.73227 0.19936 1.45975 0.16798 0.47135 0.10049 0.39706 0.08465 59316.546707 0.000570 0.34203 0.05637 0.96447 0 1.84253 0.15377 1.53594 0.12818 0.63021 0.08956 0.52488 0.07459 59316.547795 0.000518 0.41158 0.06943 0.96089 0 1.70158 0.15464 1.41089 0.12818 0.70033 0.09954 0.57981 0.08240 59316.548634 0.000315 0.25247 0.06174 0.97248 0 1.88474 0.20798 1.56682 0.17291 0.47585 0.10385 0.39689 0.08661 59316.549505 0.000556 0.43757 0.07518 0.98958 0 1.43352 0.13696 1.19451 0.11411 0.62726 0.08958 0.52257 0.07463 59316.550625 0.000564 0.40218 0.06796 0.95385 0 1.58937 0.14351 1.32526 0.11966 0.63921 0.09129 0.53381 0.07623 59316.551750 0.000561 0.38204 0.06396 0.97423 0 1.67835 0.14854 1.39901 0.12379 0.64121 0.09112 0.53362 0.07580 59316.552890 0.000579 0.37999 0.06429 0.98500 0 1.61709 0.14512 1.33818 0.12010 0.61448 0.08813 0.50749 0.07279 59316.554502 0.001033 0.40873 0.04992 0.96919 0 1.63741 0.10853 1.35139 0.08957 0.66927 0.06866 0.55330 0.05676
