/* ** ** 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 55361.040529 0.000480 0.20564 0.03221 0.99398 0 3.40964 0.22342 2.94043 0.19266 0.70116 0.09977 0.60380 0.08591 55361.041692 0.000683 0.16144 0.02227 0.95919 0 3.89035 0.19782 3.36922 0.17132 0.62805 0.08055 0.54393 0.06977 55361.308184 0.000350 0.15508 0.03477 0.95868 0 3.06504 0.25226 2.56605 0.21119 0.47534 0.09912 0.39721 0.08282 55361.309115 0.000582 0.16284 0.02479 0.98507 0 3.74689 0.21633 3.15432 0.18211 0.61016 0.08595 0.51338 0.07230 55361.310307 0.000611 0.15334 0.02366 0.95735 0 3.79843 0.21065 3.18511 0.17661 0.58245 0.08388 0.48815 0.07027 55361.311390 0.000472 0.22208 0.03569 0.95706 0 3.37073 0.22867 2.81617 0.19104 0.74858 0.10906 0.62543 0.09111 55361.312533 0.000671 0.14293 0.02211 0.97845 0 3.60859 0.19539 3.02613 0.16383 0.51579 0.07472 0.43210 0.06257 55361.313571 0.000367 0.10623 0.02606 0.97638 0 3.52897 0.26197 2.93997 0.21822 0.37489 0.08766 0.31054 0.07262 55361.314587 0.000648 0.18628 0.02779 0.97768 0 3.17418 0.18702 2.66133 0.15678 0.59127 0.08103 0.49600 0.06797
