/* ** ** 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 59757.091394 0.000373 0.33443 0.02759 0.98450 0 10.41192 0.42904 9.40951 0.38771 3.48201 0.24884 3.14193 0.22456 59757.092155 0.000388 0.32407 0.02645 0.99254 0 10.26768 0.41857 9.29085 0.37880 3.32749 0.23530 3.01253 0.21302 59757.092904 0.000362 0.35457 0.02971 0.99200 0 10.01765 0.42735 8.98853 0.38345 3.55199 0.25621 3.18710 0.22989 59757.093648 0.000382 0.30854 0.02540 1.00000 0 10.87831 0.43334 9.79557 0.39018 3.35638 0.24187 3.02566 0.21799 59757.094400 0.000370 0.33650 0.02786 0.97656 0 10.51276 0.43958 9.49023 0.39684 3.53753 0.25281 3.19220 0.22815 59757.095182 0.000411 0.28784 0.02330 0.99296 0 10.90347 0.42358 9.86564 0.38323 3.13842 0.22286 2.84289 0.20185 59757.095931 0.000339 0.37222 0.03175 1.00000 0 10.01409 0.44310 9.02593 0.39938 3.72740 0.27178 3.36375 0.24524 59757.096628 0.000359 0.34436 0.02859 0.99194 0 10.36052 0.43741 9.41247 0.39738 3.56774 0.25500 3.24411 0.23186 59757.097372 0.000385 0.33056 0.02715 0.99248 0 10.09490 0.41687 9.18186 0.37915 3.33698 0.23696 3.03673 0.21561 59757.098110 0.000353 0.32870 0.02740 0.99180 0 11.04195 0.45633 9.94735 0.41107 3.62944 0.26281 3.26761 0.23665 59757.098822 0.000359 0.32018 0.02610 0.99194 0 11.32624 0.45705 10.22389 0.41256 3.62638 0.25685 3.27521 0.23196 59757.099565 0.000385 0.32731 0.02757 1.00000 0 9.89308 0.41372 8.98593 0.37574 3.23814 0.23675 2.94402 0.21521 59757.100662 0.000712 0.32566 0.01945 0.98374 0 10.73459 0.31415 9.75792 0.28554 3.49579 0.18201 3.17730 0.16545
