/* ** ** 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 58316.137665 0.000651 0.13100 0.03209 0.97333 0 1.75310 0.14572 1.36345 0.11329 0.22966 0.05291 0.17825 0.04104 58316.138962 0.000645 0.13462 0.03209 0.96861 0 1.75366 0.14468 1.38380 0.11414 0.23608 0.05279 0.18549 0.04148 58316.140125 0.000518 0.16108 0.03892 0.98324 0 1.79631 0.16430 1.40649 0.12863 0.28936 0.06471 0.22765 0.05090 58316.141265 0.000622 0.13657 0.03260 0.96744 0 1.79716 0.15007 1.41245 0.11795 0.24545 0.05489 0.19263 0.04307 58316.142393 0.000506 0.16570 0.04069 0.97714 0 1.77246 0.16679 1.39029 0.13080 0.29369 0.06662 0.23130 0.05248 58316.143406 0.000506 0.15715 0.03833 0.96571 0 1.89219 0.16946 1.49329 0.13373 0.29736 0.06746 0.23404 0.05310 58316.144590 0.000677 0.12148 0.02880 0.95726 0 1.89252 0.14897 1.47281 0.11593 0.22990 0.05141 0.17887 0.04000 58316.146080 0.000813 0.10594 0.02494 0.96441 0 1.77161 0.13059 1.38916 0.10238 0.18768 0.04197 0.14785 0.03306 58316.147382 0.000489 0.16057 0.03874 0.96450 0 1.96134 0.17759 1.52649 0.13821 0.31493 0.07043 0.24581 0.05496 58316.148574 0.000703 0.15349 0.03302 0.97119 0 1.76244 0.13954 1.38229 0.10944 0.27051 0.05411 0.21222 0.04244
