/* ** ** Swift/XRT hardness ratio for SS 433. ** 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 56937.018804 0.000402 1.47735 0.53777 0.94964 0 0.27430 0.07821 0.20292 0.05787 0.40524 0.09171 0.30011 0.06792 56937.019780 0.000573 1.61821 0.37789 0.95455 0 0.44356 0.08230 0.33070 0.06135 0.71777 0.10178 0.52879 0.07496 56937.020671 0.000318 1.22474 0.41364 0.95455 0 0.41282 0.10398 0.30900 0.07783 0.50560 0.11375 0.37943 0.08535 56937.021383 0.000394 0.97043 0.30785 0.96324 0 0.43098 0.09697 0.31872 0.07170 0.41824 0.09353 0.30585 0.06839 56937.022097 0.000321 0.91499 0.28068 0.95495 0 0.58459 0.12602 0.43189 0.09309 0.53490 0.11674 0.39689 0.08661 56937.023052 0.000634 1.61128 0.37313 0.97260 0 0.38474 0.07025 0.29034 0.05301 0.61992 0.08831 0.46708 0.06653 56937.023981 0.000295 0.71061 0.21139 0.99020 0 0.74416 0.14597 0.55411 0.10867 0.52880 0.11827 0.39670 0.08870 56937.024861 0.000584 1.56882 0.36141 0.96040 0 0.44592 0.08073 0.32620 0.05904 0.69957 0.09967 0.51283 0.07305 56937.026140 0.000694 1.08374 0.22605 0.96667 0 0.53724 0.08116 0.39215 0.05924 0.58223 0.08374 0.42493 0.06111 56937.027135 0.000301 1.48857 0.53764 0.98077 0 0.35766 0.10106 0.26113 0.07378 0.53240 0.11978 0.39059 0.08786 56937.027951 0.000515 0.97336 0.26927 0.94944 0 0.43351 0.08457 0.31604 0.06164 0.42196 0.08277 0.30821 0.06044
