/* ** ** 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 55206.026450 0.000556 0.51297 0.04484 0.98438 0 4.72557 0.24077 4.14237 0.21104 2.42408 0.17220 2.12482 0.15094 55206.027552 0.000547 0.52415 0.04637 0.97884 0 4.73317 0.24575 4.08591 0.21213 2.48089 0.17772 2.14355 0.15355 55206.028654 0.000556 0.51905 0.04587 0.98438 0 4.62566 0.24092 4.04785 0.21079 2.40093 0.17142 2.10362 0.15020 55206.029768 0.000558 0.49696 0.04351 0.97409 0 4.83121 0.24316 4.24448 0.21363 2.40092 0.17198 2.10934 0.15110 55206.030885 0.000558 0.50337 0.04442 0.98446 0 4.70594 0.24093 4.13546 0.21172 2.36885 0.17024 2.08173 0.14960 55206.032022 0.000579 0.49767 0.04337 0.98500 0 4.69589 0.23606 4.12598 0.20741 2.33701 0.16635 2.05339 0.14616 55206.033174 0.000573 0.50714 0.04463 0.98485 0 4.57272 0.23519 4.02014 0.20677 2.31903 0.16558 2.03889 0.14558 55206.034311 0.000564 0.48354 0.04183 0.98462 0 4.89822 0.24258 4.30452 0.21318 2.36850 0.16802 2.08145 0.14766 55206.035445 0.000570 0.49185 0.04344 0.98477 0 4.69154 0.23772 4.12368 0.20895 2.30754 0.16691 2.02821 0.14671 55206.036617 0.000602 0.45813 0.03945 0.98558 0 4.84077 0.23427 4.25447 0.20589 2.21770 0.15794 1.94921 0.13882 55206.038136 0.000917 0.50851 0.03487 0.97705 0 4.71549 0.18708 4.14531 0.16446 2.39788 0.13409 2.10794 0.11787 55206.093575 0.000315 0.43348 0.07576 0.92661 0 5.43550 0.52870 2.12339 0.20313 2.35618 0.34214 0.97653 0.14053 55206.094860 0.000969 0.55228 0.04925 0.96119 0 4.70800 0.25084 2.22748 0.11853 2.60013 0.18593 1.23317 0.08809 55206.097064 0.001236 0.47874 0.04200 0.85480 0 4.84202 0.24293 2.25985 0.11333 2.31808 0.16686 1.08087 0.07777 55206.099336 0.001036 0.52277 0.04594 0.96648 0 4.71154 0.24370 2.20738 0.11412 2.46305 0.17498 1.15355 0.08192 55206.101787 0.001415 0.55374 0.04215 0.96933 0 4.35613 0.19778 2.07512 0.09417 2.41218 0.14736 1.14930 0.07019
