/* ** ** 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 53871.453160 0.000631 6.22468 3.86351 0.94954 0 0.04065 0.02347 0.03051 0.01761 0.25303 0.05764 0.19019 0.04332 53871.454661 0.000871 1.97944 0.77145 0.92691 0 0.09459 0.02991 0.07129 0.02254 0.18724 0.04265 0.14111 0.03214 53871.455961 0.000428 9.72029 7.23419 0.93919 0 0.03797 0.02685 0.02862 0.02024 0.36909 0.08568 0.27822 0.06458 53871.456805 0.000417 6.26268 3.88381 0.93056 0 0.06277 0.03624 0.04732 0.02732 0.39311 0.08900 0.29554 0.06690 53871.457879 0.000657 2.07002 0.81004 0.92070 0 0.12319 0.03944 0.09210 0.02949 0.25501 0.05739 0.19059 0.04288 53871.458990 0.000454 9.93365 7.37167 0.92357 0 0.03687 0.02608 0.02744 0.01940 0.36630 0.08241 0.27472 0.06181
