/* ** ** 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 56032.173721 0.000692 0.30304 0.02463 0.97071 0 6.47956 0.25318 5.69588 0.22256 1.96357 0.13997 1.72630 0.12306 56032.174995 0.000582 0.34198 0.02840 0.99005 0 6.62944 0.27820 5.82591 0.24448 2.26710 0.16243 1.99244 0.14275 56032.176178 0.000602 0.33542 0.02789 0.99519 0 6.48412 0.27081 5.69562 0.23788 2.17488 0.15634 1.91040 0.13733 56032.177411 0.000631 0.31408 0.02582 0.98165 0 6.69538 0.26703 5.88329 0.23464 2.10290 0.15117 1.84791 0.13284 56032.178637 0.000596 0.32850 0.02782 0.99515 0 6.55925 0.27484 5.76398 0.24152 2.15471 0.15855 1.89343 0.13932 56032.179890 0.000657 0.32013 0.02637 0.96035 0 6.45007 0.25943 5.66648 0.22791 2.06487 0.14843 1.81401 0.13040 56032.181146 0.000599 0.35379 0.02965 0.97585 0 6.28071 0.26802 5.51888 0.23551 2.22205 0.16026 1.95253 0.14082 56032.182451 0.000706 0.30099 0.02446 0.96311 0 6.42554 0.24814 5.64736 0.21809 1.93401 0.13831 1.69983 0.12157 56032.183933 0.000775 0.30239 0.02315 0.99627 0 6.42042 0.23921 5.64242 0.21023 1.94148 0.12986 1.70619 0.11413
