/* ** ** 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 54598.141112 0.000318 0.27473 0.04410 0.96364 0 5.31906 0.39478 3.42554 0.25407 1.46131 0.20802 0.94008 0.13373 54598.141786 0.000356 0.27109 0.04353 0.92683 0 4.83679 0.35243 3.21426 0.23420 1.31120 0.18761 0.86956 0.12443 54598.142495 0.000353 0.25975 0.04127 0.96721 0 4.91819 0.35623 3.26853 0.23673 1.27750 0.18067 0.84887 0.12005 54598.143190 0.000341 0.30056 0.04873 0.95763 0 4.40063 0.34237 2.93379 0.22825 1.32264 0.18816 0.88184 0.12544 54598.143968 0.000437 0.28865 0.03878 0.97351 0 5.12777 0.32483 3.41667 0.21644 1.48011 0.17534 0.98427 0.11660 54598.144801 0.000396 0.22813 0.03649 0.94891 0 4.98855 0.33883 3.30883 0.22473 1.13806 0.16480 0.75456 0.10926 54598.145565 0.000367 0.28250 0.04553 0.96063 0 4.30728 0.32636 2.88956 0.21892 1.21680 0.17310 0.81679 0.11619 54598.146291 0.000359 0.22518 0.03557 0.99194 0 5.41951 0.37205 3.59619 0.24687 1.22038 0.17360 0.81015 0.11525 54598.146997 0.000347 0.27644 0.04498 0.98333 0 4.60354 0.34922 3.02505 0.22947 1.27262 0.18318 0.83569 0.12029 54598.147724 0.000379 0.22677 0.03609 0.96947 0 5.16360 0.35037 3.42294 0.23226 1.17097 0.16855 0.77647 0.11176 54598.148453 0.000350 0.25485 0.04190 0.96694 0 4.85408 0.35329 3.23638 0.23555 1.23708 0.18239 0.82511 0.12164 54598.149176 0.000373 0.24659 0.03980 0.98450 0 4.70351 0.33543 3.13261 0.22340 1.15984 0.16795 0.77239 0.11184 54598.149986 0.000437 0.29766 0.03955 0.98675 0 5.01907 0.32290 3.34098 0.21493 1.49400 0.17368 0.99495 0.11566 54598.150817 0.000394 0.24378 0.03859 0.96324 0 4.64234 0.32253 3.12242 0.21692 1.13171 0.16099 0.76067 0.10821 54598.151537 0.000327 0.28849 0.04661 0.96460 0 4.72566 0.36189 3.16945 0.24272 1.36331 0.19394 0.91421 0.13005 54598.152197 0.000333 0.24568 0.03894 0.98261 0 5.39111 0.38321 3.64586 0.25914 1.32450 0.18762 0.89498 0.12677 54598.152909 0.000379 0.20589 0.03231 0.98473 0 5.56847 0.36896 3.75700 0.24894 1.14651 0.16310 0.77247 0.10989 54598.154066 0.000778 0.22993 0.02637 0.96654 0 4.70045 0.23154 3.15696 0.15551 1.08076 0.11192 0.72601 0.07518
