/* ** ** 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 56748.143636 0.000599 0.30777 0.02567 0.99517 0 6.88764 0.27559 6.14628 0.24592 2.11981 0.15517 1.89164 0.13847 56748.144904 0.000668 0.28657 0.02323 0.98701 0 6.83780 0.26231 6.10180 0.23408 1.95948 0.13994 1.74857 0.12488 56748.146203 0.000631 0.29167 0.02401 0.99083 0 6.98465 0.27241 6.23284 0.24309 2.03722 0.14771 1.81794 0.13181 56748.147496 0.000663 0.27212 0.02214 0.97817 0 7.23741 0.27019 6.45840 0.24111 1.96946 0.14235 1.75747 0.12703 56748.148792 0.000634 0.27626 0.02263 1.00000 0 7.27314 0.27692 6.49029 0.24711 2.00931 0.14569 1.79304 0.13001 56748.150149 0.000723 0.25714 0.02061 0.99200 0 7.00577 0.25492 6.25169 0.22748 1.80146 0.12866 1.60756 0.11481 56748.151842 0.000969 0.27862 0.01839 0.98729 0 7.30886 0.22439 6.52216 0.20024 2.03640 0.11902 1.81721 0.10621 56748.194453 0.000657 0.28313 0.02303 0.98238 0 6.81655 0.25935 6.26253 0.23827 1.92996 0.13876 1.77310 0.12748 56748.195743 0.000634 0.30416 0.02498 0.96804 0 6.65659 0.26113 6.11557 0.23990 2.02470 0.14606 1.86014 0.13419 56748.196970 0.000593 0.32302 0.02673 0.99512 0 6.53114 0.26749 6.00032 0.24575 2.10971 0.15169 1.93825 0.13936 56748.198787 0.001224 0.26960 0.01649 0.98553 0 6.68024 0.18742 6.13730 0.17219 1.80102 0.09785 1.65465 0.08989 56748.260940 0.000590 0.31336 0.02560 0.99020 0 7.15920 0.28624 6.31183 0.25236 2.24338 0.15981 1.97785 0.14089 56748.262179 0.000648 0.29838 0.02449 0.99554 0 6.72280 0.26331 5.92707 0.23214 2.00594 0.14469 1.76852 0.12757 56748.263437 0.000611 0.32353 0.02697 0.98578 0 6.61195 0.27074 5.82935 0.23869 2.13917 0.15534 1.88598 0.13695 56748.264658 0.000611 0.28787 0.02374 0.98578 0 7.41131 0.28617 6.53410 0.25230 2.13346 0.15544 1.88094 0.13704 56748.265859 0.000590 0.32442 0.02676 0.98529 0 6.89629 0.28194 6.08003 0.24857 2.23733 0.16031 1.97251 0.14134 56748.267589 0.001140 0.27841 0.01726 0.98223 0 7.17551 0.20641 6.32620 0.18198 1.99777 0.10969 1.76131 0.09671
