/* ** ** 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 54559.454582 0.000356 0.27702 0.04411 0.99187 0 3.67169 0.27263 3.01214 0.22359 1.01712 0.14327 0.83318 0.11735 54559.455332 0.000394 0.24045 0.03868 0.98529 0 3.64603 0.26184 3.04653 0.21879 0.87669 0.12620 0.73581 0.10593 54559.456151 0.000425 0.23295 0.03683 0.99320 0 3.52828 0.24322 2.93502 0.20230 0.82191 0.11694 0.68249 0.09709 54559.456920 0.000344 0.30399 0.04945 0.97479 0 3.39019 0.26740 2.82629 0.22292 1.03060 0.14663 0.85900 0.12220 54559.457667 0.000402 0.20281 0.03161 0.96403 0 4.38652 0.27946 3.66462 0.23346 0.88964 0.12656 0.74361 0.10579 54559.458448 0.000379 0.24220 0.03865 0.98473 0 3.80325 0.26864 3.17751 0.22445 0.92116 0.13182 0.76838 0.10996 54559.459261 0.000434 0.20620 0.03215 0.96000 0 3.99555 0.25506 3.35604 0.21423 0.82389 0.11721 0.69197 0.09844 54559.460040 0.000344 0.25390 0.04058 0.99160 0 3.95962 0.28854 3.32576 0.24235 1.00535 0.14302 0.84444 0.12013 54559.460763 0.000379 0.23076 0.03648 0.99237 0 3.95648 0.27271 3.32483 0.22917 0.91300 0.12988 0.76649 0.10904 54559.461469 0.000327 0.30350 0.04920 1.00000 0 3.50102 0.27747 2.91790 0.23123 1.06256 0.15027 0.88643 0.12536 54559.462164 0.000367 0.21254 0.03328 0.98425 0 4.46383 0.29224 3.75089 0.24557 0.94872 0.13497 0.79715 0.11340 54559.462971 0.000440 0.21126 0.03325 0.95395 0 3.85745 0.25254 3.23707 0.21193 0.81494 0.11662 0.68360 0.09783 54559.463784 0.000373 0.24913 0.03957 0.95349 0 3.86838 0.27332 3.25202 0.22977 0.96372 0.13710 0.81011 0.11525 54559.464548 0.000391 0.21425 0.03374 0.97778 0 4.17984 0.27492 3.50421 0.23049 0.89554 0.12816 0.75092 0.10746 54559.465361 0.000422 0.21353 0.03336 0.97945 0 3.90215 0.25900 3.28020 0.21772 0.83324 0.11784 0.70047 0.09906 54559.466220 0.000437 0.21777 0.03331 0.96026 0 3.96557 0.25423 3.32869 0.21340 0.86357 0.11995 0.72504 0.10071
