/* ** ** 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 56826.191247 0.000379 0.34232 0.02848 1.00000 0 10.00541 0.41850 8.82109 0.36894 3.42505 0.24632 3.01962 0.21714 56826.192011 0.000385 0.38643 0.03309 1.00000 0 8.64762 0.39033 7.66572 0.34597 3.34174 0.24315 2.96601 0.21579 56826.192789 0.000394 0.36300 0.03085 1.00000 0 8.94594 0.39190 7.92776 0.34730 3.24734 0.23653 2.88050 0.20979 56826.193547 0.000365 0.38183 0.03199 0.98413 0 9.46546 0.41641 8.41259 0.37009 3.61417 0.25772 3.21063 0.22894 56826.194268 0.000356 0.38693 0.03297 0.97561 0 9.51356 0.42369 8.47915 0.37763 3.68106 0.26738 3.28126 0.23835 56826.194965 0.000341 0.40398 0.03393 1.00000 0 9.59066 0.43541 8.46324 0.38426 3.87440 0.27376 3.41864 0.24154 56826.195715 0.000408 0.31581 0.02617 0.99291 0 10.06423 0.40678 8.93441 0.36112 3.17840 0.22994 2.82161 0.20409 56826.196484 0.000362 0.36662 0.03067 0.98400 0 9.91061 0.42872 8.79916 0.38062 3.63346 0.26022 3.22638 0.23103 56826.197213 0.000367 0.37727 0.03136 0.98425 0 9.72121 0.42682 8.62099 0.37848 3.66748 0.25891 3.24906 0.22936 56826.197972 0.000391 0.35199 0.02933 1.00000 0 9.42922 0.40306 8.40891 0.35945 3.31895 0.23745 2.95983 0.21175 56826.198735 0.000373 0.37029 0.03111 0.97674 0 9.53694 0.41915 8.50576 0.37383 3.53141 0.25288 3.14956 0.22553 56826.199508 0.000399 0.35365 0.02967 0.99275 0 9.15436 0.39562 8.16499 0.35286 3.23741 0.23280 2.88737 0.20763 56826.200318 0.000411 0.32299 0.02696 0.97887 0 9.82195 0.40081 8.71993 0.35584 3.17237 0.23102 2.81833 0.20526 56826.201406 0.000677 0.35745 0.02250 0.98718 0 9.46206 0.30588 8.43887 0.27280 3.38225 0.18271 3.01645 0.16295
