/* ** ** 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 55637.253077 0.000431 0.29474 0.04762 0.95973 0 2.78462 0.21323 2.36653 0.18120 0.82073 0.11676 0.69689 0.09913 55637.254099 0.000590 0.22959 0.03581 0.95588 0 2.65488 0.17795 2.27060 0.15219 0.60953 0.08584 0.52133 0.07341 55637.255105 0.000417 0.30736 0.04975 0.97222 0 2.70776 0.21328 2.32694 0.18329 0.83225 0.11770 0.71548 0.10118 55637.256000 0.000477 0.24138 0.03823 0.96364 0 3.02017 0.21034 2.59614 0.18081 0.72901 0.10370 0.62676 0.08915 55637.256983 0.000506 0.25846 0.04120 0.97714 0 2.62481 0.18887 2.25490 0.16225 0.67841 0.09650 0.58278 0.08289 55637.257932 0.000443 0.24120 0.03866 0.99346 0 3.14836 0.22755 2.70514 0.19552 0.75938 0.10864 0.65226 0.09332 55637.258763 0.000388 0.27882 0.04507 0.97015 0 3.20578 0.24116 2.74271 0.20633 0.89382 0.12788 0.76265 0.10911 55637.259576 0.000425 0.28725 0.04647 0.98639 0 2.78170 0.21429 2.39256 0.18432 0.79905 0.11366 0.68728 0.09776 55637.260406 0.000405 0.31591 0.05119 0.97143 0 2.76055 0.22123 2.36453 0.18949 0.87208 0.12281 0.74749 0.10526 55637.261231 0.000420 0.27719 0.04521 0.97241 0 2.92100 0.21956 2.51066 0.18871 0.80967 0.11719 0.69590 0.10073 55637.261992 0.000341 0.32736 0.05358 0.98305 0 3.12262 0.25187 2.65364 0.21404 1.02223 0.14559 0.86755 0.12357 55637.262759 0.000425 0.31059 0.05058 0.97959 0 2.59095 0.20548 2.22734 0.17664 0.80472 0.11446 0.69205 0.09844 55637.263566 0.000376 0.30752 0.05016 0.98462 0 2.94366 0.23493 2.53141 0.20203 0.90523 0.12876 0.77856 0.11074 55637.264399 0.000457 0.25975 0.04174 0.98100 0 2.87433 0.21036 2.46138 0.18014 0.74661 0.10681 0.63965 0.09151 55637.265239 0.000382 0.32683 0.05345 0.96212 0 2.81587 0.22734 2.40336 0.19402 0.92030 0.13091 0.78469 0.11161 55637.266130 0.000509 0.24665 0.03667 0.97727 0 3.15948 0.20912 2.68558 0.17775 0.77927 0.10375 0.66092 0.08799
