/* ** ** 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 57459.238236 0.000880 0.24625 0.01987 0.97697 0 5.98192 0.21242 5.39387 0.19152 1.47305 0.10671 1.32740 0.09616 57459.239989 0.000874 0.26018 0.02085 0.96358 0 5.93647 0.21461 5.27798 0.19081 1.54453 0.11048 1.37252 0.09818 57459.241755 0.000885 0.23301 0.01860 0.98039 0 6.33533 0.21949 5.65742 0.19599 1.47622 0.10614 1.31799 0.09476 57459.243412 0.000773 0.27041 0.02180 0.98876 0 6.23987 0.23351 5.57232 0.20854 1.68730 0.12051 1.50570 0.10754 57459.245015 0.000830 0.26674 0.02150 0.97561 0 5.94313 0.21817 5.33819 0.19595 1.58524 0.11378 1.42268 0.10211 57459.247209 0.001363 0.25403 0.01634 0.98514 0 5.81321 0.16848 5.22083 0.15131 1.47675 0.08478 1.32708 0.07619
