/* ** ** 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 55682.350761 0.000382 0.24233 0.03834 0.95455 0 4.02634 0.27866 3.26238 0.22577 0.97572 0.13883 0.79081 0.11250 55682.351467 0.000324 0.30459 0.04986 0.93750 0 3.87816 0.30206 3.08386 0.24021 1.18126 0.17006 0.93896 0.13519 55682.352176 0.000385 0.25194 0.04060 0.98496 0 3.78325 0.27416 3.00166 0.21748 0.95314 0.13721 0.75261 0.10836 55682.352928 0.000367 0.26742 0.04322 0.94488 0 3.80631 0.27931 3.07244 0.22546 1.01789 0.14656 0.82159 0.11829 55682.353736 0.000440 0.20695 0.03284 0.94737 0 4.09180 0.26513 3.29018 0.21318 0.84679 0.12265 0.68101 0.09864 55682.354598 0.000422 0.23448 0.03692 0.96575 0 3.74873 0.25949 3.02848 0.20963 0.87900 0.12431 0.71040 0.10047 55682.355350 0.000330 0.27124 0.04385 0.99123 0 4.00438 0.30109 3.23358 0.24313 1.08616 0.15545 0.87714 0.12553 55682.356100 0.000420 0.24423 0.03865 0.97241 0 3.60448 0.25593 2.90920 0.20657 0.88032 0.12450 0.71040 0.10047 55682.356858 0.000339 0.27554 0.04373 0.94017 0 4.15647 0.30410 3.35336 0.24534 1.14526 0.16130 0.92404 0.13015 55682.357535 0.000339 0.29550 0.04835 0.95726 0 3.69113 0.28701 2.98026 0.23173 1.09071 0.15704 0.88028 0.12674 55682.358247 0.000373 0.25244 0.03991 0.96899 0 3.92702 0.27753 3.17400 0.22431 0.99132 0.14019 0.80133 0.11333 55682.359091 0.000472 0.19417 0.03104 0.98160 0 3.86385 0.24630 3.12243 0.19903 0.75023 0.11000 0.60635 0.08890 55682.359986 0.000422 0.21420 0.03398 0.97945 0 3.97567 0.26487 3.21525 0.21421 0.85160 0.12261 0.68945 0.09926 55682.360729 0.000321 0.32547 0.05315 0.94595 0 3.66109 0.29738 2.95953 0.24040 1.19158 0.16881 0.96305 0.13644
