/* ** ** 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 57610.900025 0.000402 0.22297 0.03524 0.97122 0 3.91553 0.26294 3.29322 0.22114 0.87303 0.12490 0.73445 0.10507 57610.900838 0.000411 0.20970 0.03275 0.94366 0 4.20957 0.27172 3.54202 0.22863 0.88277 0.12556 0.74372 0.10578 57610.901851 0.000602 0.15092 0.02326 0.97115 0 3.83683 0.21221 3.23881 0.17914 0.57906 0.08332 0.48833 0.07026 57610.902942 0.000489 0.19592 0.03046 0.95266 0 3.73297 0.23451 3.16000 0.19851 0.73136 0.10402 0.61900 0.08804 57610.904004 0.000573 0.18177 0.02803 0.97475 0 3.39032 0.20824 2.85607 0.17542 0.61625 0.08716 0.51900 0.07340 57610.905054 0.000477 0.17937 0.02733 0.98788 0 4.14113 0.24849 3.48958 0.20940 0.74280 0.10401 0.62681 0.08777 57610.906206 0.000674 0.14705 0.02207 0.98712 0 3.62180 0.19591 3.02621 0.16369 0.53257 0.07458 0.44422 0.06220 57610.907363 0.000483 0.19727 0.03052 0.97006 0 3.75526 0.23565 3.12990 0.19638 0.74078 0.10477 0.61831 0.08744 57610.908211 0.000365 0.25712 0.04112 0.96032 0 3.83627 0.27429 3.19044 0.22813 0.98636 0.14111 0.81943 0.11722 57610.909478 0.000903 0.16309 0.01962 0.97115 0 3.91272 0.17592 3.29034 0.14794 0.63813 0.07122 0.53713 0.05994
