/* ** ** 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 57905.050324 0.000671 0.17152 0.02804 0.97414 0 2.74951 0.17194 2.29663 0.14362 0.47161 0.07123 0.39434 0.05955 57905.051325 0.000330 0.15352 0.03742 0.98246 0 2.75111 0.24455 2.29775 0.20425 0.42236 0.09586 0.35315 0.08012 57905.051965 0.000310 0.18063 0.04453 0.94393 0 2.57469 0.24818 2.17183 0.20935 0.46508 0.10552 0.39161 0.08885 57905.052636 0.000362 0.13233 0.03166 1.00000 0 2.88680 0.24563 2.40943 0.20499 0.38200 0.08542 0.32053 0.07167 57905.053354 0.000356 0.13018 0.03141 0.97561 0 3.04508 0.24927 2.52376 0.20656 0.39640 0.08997 0.32960 0.07478 57905.054202 0.000492 0.15554 0.03040 0.97647 0 2.95651 0.21133 2.45995 0.17583 0.45985 0.08367 0.38277 0.06967 57905.055029 0.000336 0.15211 0.03710 0.98276 0 2.72379 0.24404 2.28102 0.20435 0.41432 0.09399 0.34695 0.07872 57905.055735 0.000370 0.14973 0.03308 0.94531 0 3.17132 0.24854 2.63439 0.20644 0.47486 0.09810 0.39311 0.08122 57905.056629 0.000524 0.15972 0.02910 0.97238 0 3.02498 0.20584 2.49791 0.16997 0.48314 0.08167 0.39839 0.06734 57905.057700 0.000547 0.24159 0.03839 0.97354 0 2.71781 0.19262 2.24595 0.15916 0.65660 0.09339 0.54159 0.07704 57905.058614 0.000367 0.13006 0.03142 0.96850 0 2.97255 0.24635 2.45759 0.20368 0.38661 0.08772 0.32157 0.07296 57905.059607 0.000625 0.17437 0.02706 0.97685 0 3.25288 0.19539 2.70091 0.16225 0.56720 0.08115 0.46985 0.06722 57905.060669 0.000437 0.20009 0.03887 0.98013 0 2.60952 0.21012 2.16022 0.17392 0.52214 0.09231 0.43315 0.07657
