/* ** ** 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 56352.837389 0.000639 0.42669 0.07282 0.96380 0 3.56190 0.33581 1.09697 0.10342 1.51984 0.21622 0.46783 0.06655 56352.838370 0.000341 0.34869 0.09379 0.98305 0 3.13557 0.43551 0.96456 0.13397 1.09334 0.25185 0.33644 0.07749 56352.839041 0.000330 0.37944 0.10262 0.95614 0 3.06388 0.43406 0.94514 0.13388 1.16255 0.26782 0.35804 0.08247 56352.839701 0.000330 0.38580 0.10003 0.92982 0 3.31522 0.44776 1.01970 0.13770 1.27900 0.28306 0.39198 0.08675 56352.840630 0.000599 0.62111 0.11355 0.92754 0 2.69830 0.30983 0.83381 0.09575 1.67595 0.23843 0.51899 0.07383 56352.841538 0.000310 0.35064 0.09551 0.94393 0 3.53993 0.49443 1.08976 0.15221 1.24125 0.29026 0.38125 0.08915 56352.842192 0.000344 0.43289 0.11161 0.93277 0 2.94608 0.41437 0.90569 0.12738 1.27533 0.27558 0.39237 0.08478 56352.842866 0.000330 0.29500 0.07727 0.98246 0 3.90785 0.51131 1.19657 0.15656 1.15280 0.26160 0.35310 0.08013 56352.843540 0.000344 0.35524 0.09035 0.93277 0 3.55643 0.45977 1.09156 0.14112 1.26340 0.27671 0.38769 0.08491 56352.844191 0.000307 0.48529 0.13718 0.95283 0 2.60718 0.42708 0.79760 0.13066 1.26524 0.29147 0.38640 0.08900 56352.844816 0.000318 0.43220 0.11615 0.94545 0 2.89503 0.43158 0.89173 0.13293 1.25122 0.27978 0.38526 0.08615 56352.845520 0.000385 0.42420 0.10227 0.94737 0 3.02713 0.39660 0.92688 0.12144 1.28410 0.25987 0.39336 0.07960 56352.846292 0.000388 0.39634 0.10535 0.94776 0 2.58662 0.37167 0.79701 0.11452 1.02519 0.22924 0.31549 0.07054 56352.847042 0.000362 0.35135 0.09475 0.99200 0 2.91729 0.40915 0.89681 0.12578 1.02499 0.23610 0.31473 0.07249 56352.848005 0.000596 0.63030 0.11102 0.96117 0 2.77466 0.30594 0.85061 0.09379 1.74886 0.24023 0.53625 0.07366
