/* ** ** 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 53561.651284 0.000298 0.35472 0.05853 0.98058 0 3.31439 0.28172 2.79563 0.23763 1.17568 0.16627 0.99175 0.14025 53561.651901 0.000318 0.33929 0.05464 0.95455 0 3.44965 0.27775 2.90632 0.23400 1.17044 0.16322 0.98722 0.13767 53561.652540 0.000321 0.35426 0.05793 0.94595 0 3.21602 0.26736 2.73300 0.22721 1.13929 0.16044 0.96815 0.13634 53561.653327 0.000460 0.33160 0.04495 0.96226 0 3.45066 0.23109 2.92957 0.19620 1.14425 0.13485 0.97157 0.11449 53561.654204 0.000417 0.33451 0.04684 0.96528 0 3.47727 0.24271 2.95104 0.20598 1.16317 0.14122 0.98705 0.11983 53561.655665 0.001045 0.40241 0.03395 0.96399 0 3.35184 0.15046 2.83605 0.12730 1.34882 0.09637 1.14099 0.08151 53561.657184 0.000475 0.33569 0.04388 0.98171 0 3.46880 0.23018 2.94651 0.19552 1.16443 0.13114 0.98905 0.11139 53561.658081 0.000422 0.35955 0.05037 0.99315 0 3.20998 0.23325 2.72715 0.19816 1.15415 0.13824 0.98056 0.11745 53561.658825 0.000321 0.40961 0.07005 0.93694 0 2.71114 0.24675 2.30334 0.20964 1.11052 0.16077 0.94334 0.13657 53561.660234 0.001088 0.38870 0.03296 0.94947 0 3.32892 0.14644 2.82238 0.12416 1.29395 0.09380 1.09780 0.07958 53561.662430 0.001108 0.39708 0.03357 0.95300 0 3.21551 0.14435 2.73249 0.12267 1.27683 0.09148 1.08502 0.07774 53561.664609 0.001071 0.39597 0.03353 0.96216 0 3.29851 0.14721 2.79768 0.12486 1.30612 0.09399 1.10811 0.07974 53561.666678 0.000992 0.46658 0.04028 0.98542 0 2.99931 0.14659 2.53220 0.12376 1.39942 0.09958 1.18219 0.08411 53561.667974 0.000304 0.38939 0.06468 0.98095 0 2.99797 0.26785 2.54741 0.22759 1.16739 0.16347 0.99194 0.13890 53561.669311 0.001033 0.38965 0.03303 0.96078 0 3.50578 0.15651 2.95183 0.13178 1.36604 0.09845 1.14861 0.08278 53561.671328 0.000984 0.38004 0.03545 0.95588 0 3.06988 0.14873 2.59418 0.12568 1.16668 0.09299 0.98591 0.07858 53561.672612 0.000301 0.33996 0.05677 0.97115 0 3.38539 0.28673 2.87234 0.24327 1.15089 0.16564 0.97646 0.14053 53561.673970 0.001056 0.40831 0.03463 0.95890 0 3.26924 0.14836 2.76974 0.12569 1.33486 0.09564 1.13152 0.08107 53561.676313 0.001288 0.45433 0.03592 0.94459 0 2.95058 0.12837 2.50241 0.10887 1.34053 0.08848 1.13691 0.07504
