/* ** ** 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 57602.925751 0.000457 0.18882 0.02929 0.98101 0 3.95183 0.24434 3.40420 0.21049 0.74618 0.10616 0.64283 0.09146 57602.926738 0.000530 0.16874 0.02653 0.95628 0 3.88123 0.22836 3.29581 0.19391 0.65491 0.09548 0.55730 0.08123 57602.927765 0.000498 0.18880 0.02909 0.94767 0 3.81282 0.23296 3.26098 0.19923 0.71984 0.10181 0.61452 0.08691 57602.928738 0.000475 0.21663 0.03407 0.98780 0 3.30661 0.22151 2.83687 0.19004 0.71632 0.10191 0.61506 0.08750 57602.929675 0.000463 0.19679 0.03080 0.96250 0 3.79416 0.24023 3.27063 0.20709 0.74667 0.10687 0.64358 0.09211 57602.930615 0.000477 0.17003 0.02617 0.96970 0 4.33430 0.25478 3.67177 0.21582 0.73694 0.10485 0.62274 0.08860 57602.931657 0.000564 0.16278 0.02555 0.97949 0 3.67331 0.21394 3.13317 0.18247 0.59793 0.08715 0.51062 0.07442 57602.932725 0.000503 0.18148 0.02795 0.97701 0 3.83262 0.23357 3.24221 0.19759 0.69555 0.09837 0.58922 0.08333 57602.933703 0.000475 0.20071 0.03132 0.99390 0 3.60300 0.23108 3.04861 0.19551 0.72315 0.10288 0.61128 0.08697 57602.934580 0.000402 0.27300 0.04390 0.98561 0 3.12396 0.23413 2.67159 0.20019 0.85284 0.12133 0.72729 0.10347 57602.935436 0.000454 0.19851 0.03074 0.96815 0 3.91563 0.24720 3.31511 0.20929 0.77729 0.10993 0.65899 0.09320 57602.936695 0.000804 0.20986 0.02481 0.99281 0 3.56370 0.17652 3.03553 0.15034 0.74787 0.08027 0.63492 0.06814
