/* ** ** 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 59412.009386 0.000483 0.20920 0.03261 0.97006 0 3.80588 0.24923 2.95095 0.19322 0.79621 0.11262 0.61831 0.08744 59412.010266 0.000396 0.21769 0.03475 0.97810 0 4.17751 0.28094 3.36253 0.22614 0.90940 0.13166 0.73214 0.10599 59412.010954 0.000292 0.28610 0.04671 1.00000 0 4.26878 0.33577 3.43137 0.26990 1.22129 0.17474 0.98155 0.14044 59412.011776 0.000530 0.14616 0.02277 0.98361 0 4.61784 0.25555 3.70458 0.20502 0.67496 0.09829 0.54217 0.07896 59412.012725 0.000420 0.18665 0.02917 1.00000 0 4.59237 0.28851 3.66242 0.23008 0.85716 0.12266 0.68370 0.09782 59412.013573 0.000428 0.19739 0.03103 0.96622 0 4.38056 0.27678 3.49427 0.22077 0.86468 0.12448 0.68966 0.09926 59412.014450 0.000448 0.20316 0.03153 0.95484 0 4.19818 0.26844 3.33525 0.21325 0.85292 0.12063 0.67680 0.09571 59412.015205 0.000307 0.26742 0.04290 0.98113 0 4.45852 0.33052 3.58266 0.26559 1.19229 0.16960 0.95819 0.13630 59412.016018 0.000506 0.17135 0.02708 0.95429 0 4.25668 0.25275 3.39602 0.20162 0.72936 0.10684 0.58129 0.08516 59412.016958 0.000434 0.17815 0.02762 0.94667 0 4.95498 0.29565 3.91611 0.23364 0.88274 0.12632 0.69814 0.09989 59412.017766 0.000373 0.27327 0.03928 0.98450 0 4.51141 0.30213 3.61554 0.24214 1.23281 0.15678 0.98567 0.12534 59412.018781 0.000642 0.20978 0.02674 0.95495 0 4.28137 0.22596 3.38633 0.17870 0.89814 0.10422 0.71089 0.08249
