/* ** ** 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 57922.116679 0.000501 0.13046 0.03147 0.94798 0 2.16865 0.17597 1.85167 0.15024 0.28292 0.06426 0.24099 0.05473 57922.117793 0.000613 0.11694 0.02742 0.98113 0 1.97767 0.15254 1.71110 0.13197 0.23127 0.05122 0.19964 0.04421 57922.118875 0.000469 0.14433 0.03615 0.96296 0 1.97363 0.17437 1.70186 0.15036 0.28486 0.06676 0.24636 0.05775 57922.119897 0.000553 0.12721 0.03070 0.96335 0 1.95137 0.15940 1.68722 0.13781 0.24824 0.05637 0.21479 0.04878 57922.120999 0.000550 0.12634 0.03045 0.97895 0 1.93942 0.15664 1.68205 0.13585 0.24503 0.05565 0.21248 0.04826 57922.122087 0.000538 0.15014 0.03612 0.97849 0 1.69466 0.15018 1.46624 0.12995 0.25444 0.05690 0.22015 0.04923 57922.122964 0.000339 0.20506 0.05052 0.98291 0 1.95988 0.20263 1.69770 0.17552 0.40190 0.08987 0.34841 0.07791 57922.123829 0.000527 0.12757 0.03034 0.98352 0 2.02144 0.16358 1.75543 0.14205 0.25788 0.05766 0.22384 0.05005 57922.124827 0.000472 0.13096 0.03124 0.99387 0 2.17655 0.18093 1.88901 0.15703 0.28504 0.06374 0.24733 0.05530 57922.125794 0.000495 0.12314 0.02920 0.97076 0 2.25777 0.17799 1.95899 0.15444 0.27803 0.06217 0.24137 0.05397 57922.126778 0.000489 0.13797 0.03300 0.99408 0 1.99191 0.16899 1.72853 0.14665 0.27482 0.06145 0.23849 0.05333 57922.127854 0.000587 0.13454 0.02968 0.98030 0 2.05513 0.15751 1.77857 0.13629 0.27650 0.05719 0.23887 0.04939
