/* ** ** 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 59293.121076 0.000402 0.19274 0.02972 1.00000 0 4.49797 0.28243 3.79620 0.23836 0.86692 0.12208 0.73139 0.10299 59293.121875 0.000396 0.18339 0.02866 0.96350 0 4.83845 0.29449 4.08017 0.24832 0.88734 0.12770 0.74732 0.10752 59293.122746 0.000475 0.15357 0.02383 0.95732 0 4.85693 0.27183 4.07171 0.22787 0.74590 0.10795 0.62509 0.09046 59293.123625 0.000405 0.19425 0.03047 0.99286 0 4.37784 0.28172 3.68084 0.23684 0.85038 0.12164 0.71333 0.10204 59293.124395 0.000365 0.20888 0.03258 0.99206 0 4.57116 0.29846 3.87733 0.25317 0.95482 0.13523 0.80925 0.11460 59293.125095 0.000336 0.22068 0.03267 0.99138 0 5.30421 0.33609 4.45406 0.28221 1.17051 0.15660 0.98414 0.13167 59293.125813 0.000382 0.22591 0.03558 0.97727 0 4.03302 0.27259 3.41682 0.23094 0.91111 0.12959 0.77256 0.10988 59293.126539 0.000344 0.24477 0.03861 0.94118 0 4.34595 0.30356 3.65744 0.25545 1.06377 0.15045 0.89435 0.12648 59293.127283 0.000399 0.19741 0.03070 0.97101 0 4.50814 0.28324 3.77792 0.23736 0.88997 0.12658 0.74373 0.10578 59293.128093 0.000411 0.20762 0.03215 0.97183 0 4.24354 0.27366 3.55963 0.22951 0.88103 0.12406 0.73669 0.10374 59293.128900 0.000396 0.19947 0.03086 0.99270 0 4.43355 0.28422 3.74609 0.24010 0.88436 0.12453 0.74752 0.10526 59293.129661 0.000365 0.20630 0.03214 0.99206 0 4.61816 0.30187 3.88385 0.25384 0.95270 0.13474 0.80133 0.11333 59293.130636 0.000611 0.21513 0.02594 0.95735 0 4.64291 0.23408 3.89901 0.19656 0.99884 0.10943 0.83546 0.09154
