/* ** ** 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 55931.019972 0.000298 0.37723 0.06352 0.99029 0 2.97831 0.26406 2.57583 0.22838 1.12350 0.16083 0.97153 0.13908 55931.020661 0.000391 0.34720 0.05809 0.97778 0 2.49411 0.21232 2.15226 0.18322 0.86596 0.12473 0.74668 0.10755 55931.022018 0.000966 0.41633 0.03993 0.96108 0 2.73175 0.14139 2.35626 0.12194 1.13731 0.09184 0.98021 0.07914 55931.023696 0.000712 0.43156 0.04815 0.96341 0 2.64069 0.16277 2.29037 0.14118 1.13961 0.10600 0.98841 0.09193 55931.024715 0.000307 0.36498 0.06048 0.97170 0 3.10102 0.26631 2.68941 0.23096 1.13180 0.16039 0.98155 0.13909 55931.025325 0.000304 0.35335 0.06017 1.00000 0 3.01322 0.26031 2.61328 0.22576 1.06472 0.15623 0.92339 0.13549 55931.025965 0.000336 0.37427 0.06404 0.98276 0 2.63439 0.23582 2.28500 0.20455 0.98597 0.14377 0.85518 0.12470 55931.026656 0.000356 0.33996 0.05658 0.96748 0 2.84523 0.23727 2.43956 0.20344 0.96727 0.13933 0.82825 0.11929 55931.027568 0.000556 0.38795 0.04800 0.98438 0 2.91946 0.19192 2.53176 0.16643 1.13261 0.11873 0.98221 0.10296 55931.028575 0.000451 0.44788 0.06302 0.98077 0 2.51687 0.19664 2.18278 0.17054 1.12726 0.13193 0.97763 0.11442 55931.029454 0.000428 0.38052 0.05695 0.98285 0 2.64172 0.20733 2.27980 0.17890 1.00523 0.12811 0.86671 0.11042 55931.752219 0.000596 0.38547 0.06797 0.97573 0 3.16272 0.30188 1.24519 0.11415 1.21913 0.18075 0.49578 0.07052 55931.753339 0.000524 0.50093 0.08815 0.96133 0 2.85499 0.29529 1.14417 0.11824 1.43015 0.20360 0.57272 0.08147 55931.754360 0.000498 0.39909 0.08265 0.96512 0 2.54655 0.28482 1.00416 0.11226 1.01629 0.17713 0.39825 0.06933 55931.755353 0.000495 0.55887 0.10249 0.96491 0 2.70181 0.30314 1.05413 0.11810 1.50995 0.21905 0.59461 0.08608 55931.756377 0.000530 0.53242 0.09564 0.97268 0 2.80139 0.29623 1.05258 0.11130 1.49151 0.21657 0.55666 0.08069 55931.757474 0.000567 0.52415 0.09275 0.95408 0 2.66094 0.27680 1.01196 0.10518 1.39474 0.19965 0.53015 0.07585 55931.758605 0.000564 0.51377 0.08984 0.96410 0 2.80709 0.28857 1.03928 0.10680 1.44219 0.20400 0.53280 0.07535 55931.759760 0.000590 0.49837 0.08755 0.96569 0 2.68646 0.27650 1.01193 0.10399 1.33885 0.19061 0.50585 0.07195 55931.760932 0.000582 0.48880 0.08419 0.95522 0 2.97882 0.29541 1.08574 0.10766 1.45606 0.20506 0.52946 0.07456 55931.762028 0.000515 0.59383 0.10825 0.97191 0 2.55750 0.28558 0.97174 0.10826 1.51871 0.21883 0.57008 0.08204 55931.762876 0.000333 0.46927 0.12812 0.97391 0 2.14394 0.33559 0.76249 0.11930 1.00608 0.22505 0.35774 0.07999 55931.763547 0.000339 0.36947 0.09636 0.96581 0 2.68743 0.37145 0.98750 0.13639 0.99291 0.21961 0.36775 0.08137 55931.764577 0.000692 0.49262 0.08352 0.97490 0 2.57190 0.25483 0.93629 0.09277 1.26696 0.17430 0.45988 0.06326
