/* ** ** 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 56719.928383 0.000642 0.30421 0.02494 0.98649 0 6.55659 0.25806 5.92554 0.23320 1.99455 0.14344 1.80521 0.12982 56719.929725 0.000700 0.25822 0.02053 0.97521 0 7.34039 0.26341 6.56999 0.23575 1.89546 0.13450 1.69323 0.12013 56719.931085 0.000660 0.28837 0.02356 0.97807 0 6.87606 0.26216 6.16260 0.23495 1.98282 0.14331 1.77646 0.12839 56719.932298 0.000553 0.32054 0.02652 1.00000 0 7.19785 0.29416 6.44748 0.26350 2.30721 0.16594 2.06984 0.14886 56719.933394 0.000544 0.33201 0.02766 0.98936 0 7.07824 0.29169 6.36149 0.26213 2.35006 0.17019 2.11403 0.15307 56719.934572 0.000634 0.31139 0.02555 0.96804 0 6.69037 0.26414 5.99242 0.23656 2.08333 0.14982 1.86481 0.13411 56719.935819 0.000613 0.29491 0.02399 0.99528 0 7.07938 0.27572 6.38940 0.24882 2.08777 0.14914 1.88375 0.13456 56719.937020 0.000587 0.30550 0.02512 0.99015 0 7.18698 0.28657 6.44501 0.25696 2.19563 0.15788 1.96687 0.14145 56719.938597 0.000990 0.28339 0.01825 0.99123 0 7.34003 0.22026 6.63396 0.19906 2.08012 0.11855 1.87975 0.10714
