/* ** ** 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 55325.765703 0.000683 0.25336 0.02027 0.97034 0 9.33463 0.33250 6.83534 0.24280 2.36501 0.16944 1.74035 0.12435 55325.767029 0.000642 0.26234 0.02090 0.98649 0 8.83662 0.32151 7.02314 0.25552 2.31821 0.16429 1.84283 0.13059 55325.768258 0.000587 0.28405 0.02294 0.96552 0 9.05385 0.34059 7.15257 0.26906 2.57176 0.18379 2.03337 0.14529 55325.769500 0.000654 0.25724 0.02083 0.98673 0 8.78455 0.31970 6.87071 0.25002 2.25978 0.16348 1.76430 0.12764 55325.770834 0.000680 0.25312 0.02047 0.97447 0 8.73438 0.31543 6.78459 0.24501 2.21085 0.15994 1.71808 0.12429 55325.772124 0.000611 0.28420 0.02300 0.99052 0 8.72250 0.33218 6.69451 0.25495 2.47891 0.17701 1.90225 0.13583 55325.773386 0.000651 0.27254 0.02201 0.98222 0 8.46410 0.31549 6.59144 0.24566 2.30683 0.16527 1.79428 0.12854 55325.775223 0.001186 0.26771 0.01560 0.98780 0 9.08023 0.24301 6.98455 0.18691 2.43083 0.12583 1.86932 0.09675
