/* ** ** 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 58704.552837 0.000310 0.25575 0.06489 0.99065 0 1.76634 0.20069 1.49789 0.17019 0.45174 0.10248 0.38330 0.08696 58704.553497 0.000350 0.20867 0.05028 0.99174 0 1.99189 0.20338 1.68142 0.17167 0.41566 0.09071 0.35058 0.07650 58704.554157 0.000310 0.20882 0.05095 0.99065 0 2.21117 0.22840 1.87894 0.19408 0.46174 0.10206 0.39236 0.08673 58704.554967 0.000501 0.15396 0.03794 0.96532 0 1.78880 0.15948 1.52113 0.13562 0.27541 0.06328 0.23417 0.05380 58704.555815 0.000347 0.18086 0.04397 0.98333 0 2.22208 0.21209 1.87813 0.17923 0.40188 0.08987 0.33955 0.07593 58704.556532 0.000370 0.16876 0.04150 0.99219 0 2.17370 0.20743 1.84708 0.17627 0.36683 0.08314 0.31171 0.07065 58704.557299 0.000396 0.17617 0.04340 0.97080 0 1.98802 0.19189 1.68967 0.16309 0.35023 0.07938 0.29764 0.06746 58704.558130 0.000434 0.15119 0.03629 0.96667 0 2.15038 0.18760 1.82761 0.15944 0.32511 0.07270 0.27632 0.06179 58704.558986 0.000422 0.16150 0.03806 0.95890 0 2.21940 0.19749 1.86285 0.16577 0.35843 0.07822 0.30050 0.06557 58704.559773 0.000365 0.18745 0.04688 0.98413 0 1.97931 0.19560 1.68217 0.16624 0.37102 0.08524 0.31538 0.07246 58704.560436 0.000298 0.25298 0.06432 0.98058 0 1.83595 0.21152 1.55414 0.17905 0.46445 0.10526 0.39195 0.08883 58704.561232 0.000498 0.11204 0.02684 0.99419 0 2.47490 0.19165 2.07170 0.16041 0.27730 0.06285 0.23150 0.05247 58704.562056 0.000327 0.23317 0.05871 0.95575 0 1.87397 0.20535 1.56817 0.17183 0.43695 0.09905 0.36654 0.08307 58704.562774 0.000391 0.28331 0.06743 0.98519 0 1.52853 0.17398 1.27678 0.14534 0.43304 0.09052 0.36213 0.07566
