/* ** ** Swift/XRT hardness ratio for Cir X-1. ** 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 55377.820653 0.000407 20.58475 21.10393 0.89286 1 0.01957 0.01957 0.01481 0.01481 0.40275 0.09102 0.31682 0.07159 55377.821510 0.000421 22.39797 22.91586 0.93103 1 0.01813 0.01813 0.01429 0.01429 0.40614 0.08784 0.32151 0.06954 55377.823137 0.000392 11.51820 8.95298 0.81481 1 0.04192 0.03126 0.03306 0.02466 0.48282 0.10589 0.38002 0.08334 55377.823906 0.000378 19.09437 19.57594 0.92308 1 0.02211 0.02211 0.01739 0.01739 0.42226 0.09543 0.33003 0.07457 55377.825461 0.000392 16.25885 16.67304 0.85185 1 0.02678 0.02678 0.02105 0.02105 0.43535 0.09889 0.34265 0.07783 55377.826201 0.000349 14.89691 15.27252 0.99994 1 0.02810 0.02810 0.02222 0.02222 0.41859 0.09459 0.33005 0.07458 55377.831024 0.000901 42.64500 43.10436 0.92855 1 0.00961 0.00961 0.00761 0.00761 0.40990 0.06033 0.32380 0.04765 55377.888958 0.000697 42.07913 42.50844 0.97917 1 0.01272 0.01272 0.01000 0.01000 0.53519 0.07664 0.42047 0.06022 55377.890062 0.000349 26.77324 34.27166 0.87500 1 0.01772 0.02232 0.01394 0.01756 0.47440 0.10833 0.37340 0.08527 55377.890948 0.000537 18.18027 18.66330 0.91892 1 0.01590 0.01590 0.01250 0.01250 0.28898 0.06706 0.22713 0.05270 55377.891834 0.000349 9.49397 7.03493 1.00000 1 0.04621 0.03268 0.03636 0.02571 0.43874 0.09718 0.34505 0.07643 55377.895669 0.000697 19.35247 19.83533 0.92280 1 0.01180 0.01180 0.00930 0.00930 0.22844 0.05135 0.17972 0.04040
