/* ** ** Swift/XRT hardness ratio for 1A 0535+262. ** 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 57279.247661 0.000349 1.82986 0.72016 1.00000 1 0.69725 0.22406 0.17912 0.05756 1.27587 0.28991 0.32838 0.07462 57279.248548 0.000537 4.58331 1.63277 1.00000 1 0.45468 0.14849 0.11761 0.03841 2.08394 0.29660 0.53733 0.07648 57279.249434 0.000349 1.75106 0.62741 0.91667 1 0.88574 0.25507 0.22826 0.06572 1.55100 0.33068 0.40000 0.08528 57279.250247 0.000465 2.41111 0.62307 0.93750 1 1.08253 0.23419 0.28004 0.06058 2.61011 0.36894 0.67406 0.09528 57279.251395 0.000683 2.83966 0.67283 0.94134 1 0.86578 0.17673 0.22325 0.04557 2.45851 0.29576 0.63385 0.07625
