/* ** ** 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 59053.922243 0.000394 0.29521 0.04825 0.95588 0 3.04798 0.23616 2.57074 0.19918 0.89980 0.12949 0.75867 0.10918 59053.922941 0.000304 0.33469 0.05501 0.99048 0 3.45630 0.28933 2.88431 0.24145 1.15680 0.16361 0.96314 0.13621 59053.923679 0.000434 0.27606 0.04436 0.96667 0 2.99543 0.22738 2.52677 0.19180 0.82691 0.11712 0.69754 0.09879 59053.924466 0.000353 0.30629 0.05023 0.94262 0 3.38405 0.27121 2.81993 0.22600 1.03651 0.14831 0.86209 0.12334 59053.925273 0.000454 0.26490 0.04294 0.92994 0 3.06106 0.22354 2.54290 0.18567 0.81088 0.11736 0.67201 0.09728 59053.926260 0.000532 0.23728 0.03768 0.97283 0 2.82709 0.19963 2.33930 0.16525 0.67080 0.09542 0.55672 0.07919 59053.927348 0.000556 0.22970 0.03613 0.96875 0 2.81846 0.19275 2.37044 0.16209 0.64739 0.09169 0.54378 0.07702 59053.928459 0.000556 0.21902 0.03454 0.98958 0 2.88924 0.19661 2.38682 0.16240 0.63279 0.09002 0.52449 0.07461 59053.929509 0.000495 0.25219 0.04025 0.98830 0 2.80448 0.20289 2.33833 0.16913 0.70727 0.10061 0.58967 0.08388 59053.930499 0.000495 0.25333 0.04011 0.97076 0 2.85899 0.20335 2.38482 0.16961 0.72428 0.10244 0.60341 0.08534 59053.931413 0.000420 0.26807 0.04291 0.95172 0 3.24692 0.23817 2.70013 0.19807 0.87039 0.12383 0.72213 0.10272 59053.932568 0.000735 0.22185 0.03086 0.99213 0 2.78553 0.16526 2.31651 0.13743 0.61798 0.07776 0.51450 0.06474
