/* ** ** 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 57525.103949 0.000486 0.20155 0.03149 0.98810 0 3.54900 0.22957 2.98032 0.19276 0.71532 0.10174 0.60038 0.08539 57525.104843 0.000408 0.21804 0.03425 0.98582 0 3.94776 0.26150 3.32551 0.22026 0.86075 0.12262 0.72417 0.10312 57525.105671 0.000420 0.21753 0.03450 0.97931 0 3.76276 0.25126 3.19391 0.21327 0.81850 0.11775 0.69476 0.09995 57525.106464 0.000373 0.20401 0.03172 0.97674 0 4.66499 0.29938 3.94634 0.25325 0.95170 0.13476 0.80288 0.11369 57525.107592 0.000755 0.15946 0.02110 0.99352 0 3.84135 0.18925 3.25916 0.16057 0.61255 0.07523 0.51952 0.06380 57525.169050 0.000307 0.18624 0.04713 0.95283 0 5.02989 0.50980 2.04833 0.20457 0.93678 0.21720 0.38644 0.08900 57525.169692 0.000336 0.13349 0.03176 0.96552 0 5.87899 0.47624 2.71412 0.21977 0.78478 0.17559 0.35774 0.07999 57525.170633 0.000605 0.23155 0.03637 0.95694 0 4.93058 0.33683 2.17311 0.14843 1.14166 0.16150 0.50083 0.07083 57525.171562 0.000324 0.17872 0.04359 0.98214 0 4.73860 0.46131 2.03069 0.19768 0.84689 0.18938 0.36424 0.08145 57525.172430 0.000544 0.23439 0.03639 0.94681 0 5.62062 0.37648 2.45178 0.16421 1.31744 0.18450 0.57399 0.08037 57525.173515 0.000541 0.22760 0.03615 0.96791 0 5.49545 0.37808 2.40533 0.16546 1.25075 0.17904 0.54768 0.07837 57525.174730 0.000674 0.17921 0.02798 0.96567 0 5.64253 0.34052 2.44401 0.14748 1.01119 0.14560 0.43827 0.06308 57525.176235 0.000830 0.25856 0.03352 0.95470 0 4.91436 0.28812 2.12557 0.12460 1.27066 0.14691 0.55189 0.06380
