/* ** ** 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 59662.385645 0.000631 0.25827 0.02079 0.98624 0 8.20792 0.30029 7.16608 0.26214 2.11986 0.15199 1.84864 0.13255 59662.386791 0.000515 0.32104 0.02646 0.98315 0 8.06165 0.33103 7.09345 0.29128 2.58813 0.18496 2.27714 0.16273 59662.387928 0.000622 0.27563 0.02240 0.97674 0 7.77349 0.29468 6.83464 0.25909 2.14263 0.15403 1.88312 0.13537 59662.389421 0.000871 0.30569 0.02074 0.97216 0 7.49455 0.24505 6.58215 0.21520 2.29098 0.13618 2.01083 0.11952 59662.845384 0.000611 0.29152 0.02377 0.98104 0 7.62739 0.29615 6.58751 0.25579 2.22351 0.15942 1.92011 0.13767 59662.846611 0.000616 0.27997 0.02277 0.98592 0 7.83387 0.29822 6.72703 0.25608 2.19325 0.15766 1.88314 0.13537 59662.847817 0.000590 0.29044 0.02356 0.98039 0 8.10253 0.31342 6.89108 0.26653 2.35332 0.16777 2.00253 0.14274 59662.848963 0.000556 0.30085 0.02474 0.98958 0 8.02664 0.31706 6.89738 0.27243 2.41482 0.17416 2.07588 0.14972 59662.850146 0.000628 0.27623 0.02262 0.98157 0 7.78488 0.29498 6.67605 0.25296 2.15045 0.15614 1.84194 0.13373 59662.851414 0.000639 0.28605 0.02307 0.98190 0 7.62935 0.28998 6.57867 0.25005 2.18239 0.15521 1.88184 0.13384
