/* ** ** 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 55677.058505 0.000312 0.26301 0.04189 0.99074 0 4.57437 0.33501 3.56151 0.26079 1.20312 0.17017 0.93614 0.13239 55677.059873 0.001056 0.30980 0.02526 0.96986 0 4.80115 0.18959 3.62456 0.14311 1.48741 0.10611 1.12303 0.08011 55677.061934 0.001004 0.32468 0.02676 0.95677 0 4.88258 0.19804 3.66558 0.14867 1.58526 0.11377 1.19120 0.08548 55677.063265 0.000327 0.24049 0.03845 0.95575 0 5.07142 0.35301 3.80151 0.26456 1.21963 0.17553 0.91306 0.13143 55677.063916 0.000324 0.26191 0.04061 0.97321 0 5.04980 0.35330 3.73465 0.26125 1.32262 0.18300 0.97820 0.13531 55677.064575 0.000336 0.23041 0.03651 0.95690 0 5.12451 0.34876 3.86815 0.26324 1.18074 0.16895 0.89305 0.12779 55677.065840 0.000929 0.33579 0.02753 0.98131 0 5.04659 0.20846 3.78529 0.15634 1.69458 0.12002 1.27031 0.08996 55677.067133 0.000365 0.21887 0.03469 0.99206 0 4.84213 0.32990 3.63014 0.24728 1.05981 0.15166 0.79303 0.11348 55677.067810 0.000312 0.27371 0.04423 0.98148 0 4.57330 0.34266 3.39649 0.25443 1.25174 0.17921 0.93518 0.13382 55677.069029 0.000906 0.36385 0.03026 0.96805 0 4.83538 0.20823 3.61384 0.15561 1.75935 0.12516 1.31548 0.09357 55677.070276 0.000341 0.25349 0.03938 0.97458 0 4.72191 0.33067 3.56087 0.24935 1.19696 0.16599 0.90586 0.12562 55677.071019 0.000402 0.26550 0.03696 0.97122 0 4.90711 0.31232 3.70284 0.23566 1.30282 0.16128 0.98272 0.12165 55677.072498 0.001076 0.30177 0.02445 0.96237 0 4.88300 0.18912 3.70063 0.14332 1.47355 0.10487 1.11608 0.07942
