/* ** ** 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 58228.124824 0.000506 0.15530 0.03794 0.98286 0 1.71387 0.15498 1.48052 0.13388 0.26616 0.06041 0.22988 0.05218 58228.125735 0.000405 0.16275 0.03982 0.97857 0 2.04245 0.18655 1.77336 0.16197 0.33240 0.07545 0.28861 0.06551 58228.126774 0.000634 0.11086 0.02619 0.98174 0 1.93611 0.14758 1.68097 0.12813 0.21463 0.04799 0.18636 0.04167 58228.127885 0.000477 0.16050 0.03872 0.96970 0 1.80859 0.16383 1.56434 0.14170 0.29028 0.06491 0.25042 0.05599 58228.128988 0.000625 0.10139 0.02418 0.97685 0 2.15110 0.15711 1.84951 0.13506 0.21810 0.04952 0.18739 0.04253 58228.130194 0.000582 0.11465 0.02678 0.95522 0 2.19040 0.16288 1.88168 0.13992 0.25112 0.05560 0.21637 0.04789 58228.131143 0.000367 0.17572 0.04341 0.96850 0 2.13019 0.20762 1.83178 0.17851 0.37431 0.08496 0.32146 0.07296 58228.132029 0.000518 0.15009 0.03606 0.98883 0 1.74676 0.15363 1.50989 0.13279 0.26217 0.05862 0.22637 0.05062 58228.133632 0.001085 0.10530 0.01975 0.96533 0 1.95542 0.11264 1.66817 0.09609 0.20590 0.03675 0.17563 0.03134
