/* ** ** 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 57862.121654 0.000318 0.18562 0.04491 0.96364 0 5.78171 0.55728 2.08837 0.19750 1.07321 0.23816 0.39689 0.08661 57862.122560 0.000582 0.21605 0.03383 0.95522 0 6.92605 0.45830 2.41510 0.15933 1.49640 0.21236 0.52170 0.07378 57862.123691 0.000550 0.23149 0.03648 0.98421 0 6.31335 0.43520 2.31452 0.15932 1.46149 0.20711 0.53565 0.07575 57862.124571 0.000330 0.16760 0.04069 0.97368 0 5.62317 0.52230 2.12902 0.19710 0.94244 0.21139 0.36096 0.08071 57862.125598 0.000697 0.17782 0.02776 0.99170 0 6.27186 0.38910 2.28432 0.14154 1.11527 0.15976 0.41477 0.05935 57862.126596 0.000301 0.19146 0.04703 0.97115 0 5.59440 0.56434 2.04235 0.20590 1.07113 0.23987 0.39670 0.08870 57862.127496 0.000593 0.21759 0.03500 0.97073 0 6.14588 0.41617 2.24026 0.15154 1.33729 0.19512 0.49032 0.07142 57862.128605 0.000515 0.15808 0.02921 0.96067 0 6.60388 0.45016 2.50843 0.17072 1.04392 0.17928 0.39832 0.06831 57862.129432 0.000312 0.15425 0.03782 0.97222 0 6.13737 0.56101 2.40031 0.21890 0.94672 0.21536 0.37665 0.08547 57862.130372 0.000628 0.20623 0.03236 0.98618 0 6.09492 0.40034 2.27912 0.14948 1.25698 0.17909 0.46564 0.06624 57862.131550 0.000550 0.21447 0.03392 0.96316 0 6.63550 0.44294 2.49211 0.16612 1.42312 0.20407 0.54169 0.07751 57862.132702 0.000602 0.14087 0.02687 0.97596 0 5.98426 0.39564 2.28315 0.15072 0.84298 0.15085 0.31800 0.05686
