/* ** ** 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 59406.021014 0.000339 0.25301 0.04010 0.95726 0 4.47343 0.31973 3.53323 0.25252 1.13184 0.16009 0.89434 0.12648 59406.021732 0.000379 0.24355 0.03454 0.96947 0 5.18949 0.32283 4.02951 0.25064 1.26391 0.16106 0.98385 0.12534 59406.022539 0.000428 0.27793 0.03775 0.96622 0 4.51511 0.28513 3.53421 0.22315 1.25487 0.15089 0.98291 0.11819 59406.023277 0.000310 0.26882 0.04243 0.97196 0 4.72781 0.34436 3.65336 0.26611 1.27095 0.17797 0.98240 0.13756 59406.023899 0.000312 0.23942 0.03872 0.97222 0 4.97119 0.35140 3.88939 0.27494 1.19019 0.17310 0.92995 0.13527 59406.024521 0.000310 0.27302 0.04424 0.97196 0 4.48782 0.33861 3.49403 0.26362 1.22526 0.17573 0.95102 0.13639 59406.025658 0.000828 0.25652 0.02479 0.96853 0 4.88750 0.21287 3.85291 0.16780 1.25376 0.10815 0.98658 0.08510 59406.027140 0.000648 0.20996 0.02339 0.95639 0 5.47512 0.25280 4.40605 0.20342 1.14955 0.11654 0.92465 0.09371
