/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 56467.219202 0.000949 0.31158 0.02536 0.99390 0 4.67260 0.18512 3.92500 0.15548 1.45590 0.10352 1.22307 0.08696 56467.221056 0.000906 0.33702 0.02795 0.98403 0 4.53430 0.18830 3.81013 0.15822 1.52816 0.10972 1.28349 0.09213 56467.222876 0.000914 0.35399 0.02945 0.96835 0 4.33360 0.18287 3.65818 0.15436 1.53404 0.10997 1.29347 0.09272 56467.224769 0.000978 0.28792 0.02329 0.98225 0 4.96205 0.18952 4.16248 0.15897 1.42866 0.10186 1.19804 0.08541 56467.226786 0.001039 0.29657 0.02397 0.97772 0 4.57276 0.17583 3.83503 0.14744 1.35615 0.09643 1.13596 0.08076 56467.228820 0.000995 0.28496 0.02452 0.96512 0 4.45389 0.17867 3.71668 0.14909 1.26920 0.09660 1.05942 0.08064
