/* ** ** 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 56717.867466 0.000631 0.29619 0.02419 1.00000 0 7.02981 0.27466 6.17623 0.24131 2.08213 0.14937 1.82785 0.13112 56717.868763 0.000666 0.27797 0.02263 0.98696 0 7.06353 0.26708 6.25541 0.23651 1.96342 0.14159 1.73773 0.12531 56717.870169 0.000741 0.25444 0.02031 0.97266 0 7.07331 0.25223 6.27510 0.22377 1.79975 0.12851 1.59665 0.11401 56717.871555 0.000639 0.31361 0.02566 0.97285 0 6.67725 0.26551 5.92494 0.23560 2.09404 0.14973 1.85816 0.13287 56717.872886 0.000692 0.28631 0.02305 0.98745 0 6.68063 0.25383 5.92801 0.22523 1.91275 0.13579 1.69747 0.12051 56717.874220 0.000642 0.32970 0.02731 0.98649 0 6.20440 0.25452 5.50443 0.22581 2.04562 0.14722 1.81478 0.13061 56717.875531 0.000663 0.30245 0.02447 0.98253 0 6.61930 0.25741 5.87258 0.22837 2.00202 0.14203 1.77615 0.12600 56717.877325 0.001131 0.30716 0.01934 0.97954 0 6.45215 0.19595 5.70617 0.17329 1.98183 0.10932 1.75159 0.09661
