/* ** ** 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 56709.524713 0.000392 0.36080 0.09700 1.00000 1 4.02012 0.55486 0.80006 0.11036 1.45045 0.33463 0.28892 0.06666 56709.553062 0.027956 0.52203 0.07882 0.03789 1 3.47159 0.30619 0.70663 0.06231 1.81228 0.22207 0.36655 0.04491 56709.581424 0.000407 0.60061 0.16782 0.96429 1 2.49082 0.43463 0.51500 0.08983 1.49602 0.32650 0.31111 0.06789 56709.582151 0.000320 0.55206 0.15411 1.00000 1 3.38536 0.58934 0.69474 0.12094 1.86892 0.40784 0.38182 0.08332 56709.582964 0.000494 0.31697 0.08340 0.97059 1 3.61309 0.47503 0.75452 0.09919 1.14525 0.26102 0.23818 0.05429 56709.583850 0.000392 0.39038 0.10315 0.96296 1 3.82062 0.53767 0.78923 0.11107 1.49150 0.33353 0.30769 0.06880 56709.584678 0.000436 0.60717 0.14479 1.00000 1 3.04863 0.45136 0.63207 0.09358 1.85102 0.34602 0.38433 0.07184 56709.585797 0.000683 0.26777 0.06497 1.00000 1 3.37258 0.37885 0.69261 0.07781 0.90307 0.19423 0.18575 0.03995 56709.586886 0.000407 0.38889 0.10306 1.00000 1 3.67890 0.51904 0.75037 0.10586 1.43068 0.32094 0.29250 0.06561 56709.587685 0.000392 0.45686 0.12338 0.96296 1 3.28544 0.49749 0.67423 0.10209 1.50098 0.33564 0.30769 0.06880 56709.588484 0.000407 0.66052 0.17158 0.92857 1 2.83902 0.46523 0.57923 0.09491 1.87524 0.37795 0.38192 0.07697 56709.589370 0.000479 0.35624 0.09329 1.00000 1 3.28858 0.44810 0.68094 0.09278 1.17152 0.26198 0.24243 0.05421 56709.590227 0.000378 0.42270 0.11168 0.96154 1 3.76751 0.53826 0.78400 0.11200 1.59254 0.35395 0.33040 0.07343 56709.591011 0.000407 0.54122 0.15015 1.00000 1 2.58411 0.42925 0.54296 0.09019 1.39856 0.31076 0.29500 0.06556 56709.591767 0.000349 0.56834 0.15733 1.00000 1 3.00423 0.51166 0.61391 0.10453 1.70742 0.37262 0.35000 0.07638 56709.592435 0.000320 0.49372 0.13704 1.00000 1 3.58068 0.58872 0.74000 0.12166 1.76785 0.39535 0.36364 0.08131 56709.593088 0.000334 0.48712 0.12874 1.00000 1 3.79636 0.59291 0.78096 0.12196 1.84926 0.39428 0.38261 0.08157 56709.593844 0.000421 0.51167 0.14161 1.00000 1 2.60509 0.42476 0.54036 0.08810 1.33296 0.29807 0.27586 0.06168 56709.595035 0.000770 0.42822 0.08751 0.98014 1 3.00536 0.33683 0.62608 0.07016 1.28694 0.21992 0.26681 0.04559
