/* ** ** 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 55396.690187 0.000680 0.16418 0.02508 0.98723 0 3.05346 0.17647 2.62488 0.15168 0.50131 0.07090 0.43175 0.06106 55396.691243 0.000376 0.14382 0.03112 0.96923 0 3.17782 0.24311 2.73160 0.20896 0.45704 0.09252 0.39333 0.07961 55396.691967 0.000347 0.14545 0.03353 0.92500 0 3.12343 0.25066 2.69481 0.21626 0.45430 0.09818 0.39233 0.08478 55396.692679 0.000365 0.14734 0.03254 0.96032 0 3.16107 0.24618 2.67915 0.20864 0.46576 0.09626 0.39302 0.08123 55396.693697 0.000654 0.16548 0.02555 0.96460 0 3.17805 0.18437 2.74780 0.15941 0.52590 0.07526 0.45467 0.06507 55396.694669 0.000318 0.13474 0.03212 0.97273 0 3.21613 0.26574 2.77901 0.22962 0.43336 0.09690 0.37446 0.08373 55396.695532 0.000544 0.17494 0.02661 0.98936 0 3.64309 0.21658 3.14030 0.18669 0.63732 0.08925 0.54930 0.07692 55396.696756 0.000680 0.15425 0.02400 0.97447 0 3.22550 0.18346 2.77868 0.15804 0.49753 0.07207 0.42825 0.06203 55396.697806 0.000370 0.11824 0.02798 0.97656 0 3.13582 0.24274 2.71120 0.20987 0.37077 0.08291 0.32053 0.07167 55396.698497 0.000321 0.14669 0.03563 0.96396 0 2.92319 0.25278 2.51142 0.21717 0.42880 0.09733 0.36955 0.08387 55396.699273 0.000448 0.23850 0.03800 0.98065 0 3.16465 0.22176 2.73412 0.19159 0.75476 0.10802 0.65209 0.09332 55396.700890 0.001169 0.15845 0.01778 0.97772 0 3.41670 0.14194 2.94716 0.12243 0.54137 0.05644 0.46660 0.04865
