/* ** ** 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 59112.880406 0.000365 0.13485 0.03226 0.96825 0 3.21538 0.27288 2.36115 0.19992 0.43359 0.09697 0.32842 0.07344 59112.881358 0.000587 0.31623 0.05196 0.95074 0 2.37627 0.19096 1.62721 0.13063 0.75144 0.10771 0.51358 0.07350 59112.882322 0.000376 0.18320 0.04467 0.96154 0 2.57223 0.25000 1.74762 0.16981 0.47122 0.10538 0.32053 0.07167 59112.883034 0.000336 0.19809 0.04745 0.96552 0 2.77728 0.27435 1.88482 0.18617 0.55014 0.12006 0.37563 0.08197 59112.883988 0.000619 0.22795 0.03610 0.97664 0 3.09227 0.21485 2.09298 0.14538 0.70489 0.10030 0.47676 0.06782 59112.884929 0.000321 0.17926 0.04423 0.97297 0 3.08360 0.29871 2.04029 0.19756 0.55276 0.12543 0.36614 0.08310 59112.885927 0.000677 0.24669 0.03898 0.95299 0 2.73685 0.19284 1.81832 0.12807 0.67516 0.09550 0.44918 0.06352 59112.887264 0.000660 0.24333 0.03930 0.96053 0 2.76059 0.19721 1.84381 0.13166 0.67172 0.09729 0.44783 0.06486 59112.888531 0.000608 0.21546 0.03753 0.98095 0 2.75739 0.20588 1.83912 0.13730 0.59411 0.09348 0.39618 0.06232 59112.889703 0.000564 0.16617 0.03210 0.97949 0 3.05710 0.22291 2.04088 0.14880 0.50799 0.09086 0.33791 0.06044
