/* ** ** 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 54273.078754 0.000959 5.13695 2.82115 0.95455 1 0.04015 0.02011 0.02500 0.01250 0.20624 0.04641 0.12637 0.02840 54273.080613 0.000901 6.28544 4.01149 0.98387 1 0.03338 0.01994 0.02073 0.01239 0.20983 0.04718 0.13051 0.02933 54273.082545 0.001031 9.52469 7.06467 0.98592 1 0.01938 0.01370 0.01212 0.00857 0.18456 0.04128 0.11429 0.02556 54273.084303 0.000726 9.81680 7.28428 0.98000 1 0.02649 0.01874 0.01667 0.01179 0.26009 0.05846 0.16247 0.03652 54273.085973 0.000944 6.71506 4.28820 1.00000 1 0.02907 0.01739 0.01814 0.01084 0.19520 0.04366 0.12308 0.02752
