/* ** ** 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 55674.773241 0.000544 0.57621 0.05178 0.98404 0 4.19058 0.22852 3.72862 0.20333 2.41464 0.17247 2.14854 0.15347 55674.774349 0.000564 0.51135 0.04527 0.97949 0 4.58853 0.23685 4.04253 0.20865 2.34634 0.16876 2.06992 0.14885 55674.775588 0.000674 0.43667 0.03736 0.97854 0 4.52560 0.21310 3.99484 0.18809 1.97621 0.14118 1.74333 0.12452 55674.776951 0.000689 0.43940 0.03824 0.97899 0 4.33026 0.20745 3.82752 0.18339 1.90273 0.13824 1.68312 0.12228 55674.778221 0.000582 0.51271 0.04548 0.98010 0 4.37256 0.22410 3.89345 0.19953 2.24185 0.16233 1.99609 0.14452 55674.779462 0.000660 0.50278 0.04416 0.98684 0 3.99010 0.20437 3.54685 0.18165 2.00614 0.14315 1.78385 0.12730 55674.780782 0.000660 0.44362 0.03904 0.98246 0 4.40124 0.21371 3.91724 0.19019 1.95248 0.14329 1.73652 0.12745 55674.782119 0.000677 0.44004 0.03780 0.98718 0 4.41026 0.20992 3.91707 0.18645 1.94070 0.13875 1.72477 0.12330 55674.783476 0.000680 0.45300 0.03949 0.97447 0 4.23237 0.20398 3.78044 0.18220 1.91725 0.13928 1.71252 0.12441 55674.784694 0.000538 0.56280 0.05028 0.97849 0 4.34988 0.23207 3.87410 0.20667 2.44813 0.17545 2.17812 0.15610 55674.786016 0.000784 0.47515 0.03674 0.98524 0 4.41061 0.19516 3.93943 0.17431 2.09569 0.13290 1.87180 0.11870
