/* ** ** 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 55859.868636 0.000379 0.42273 0.07221 0.97710 0 3.21202 0.29994 1.83545 0.17045 1.35782 0.19421 0.77851 0.11074 55859.869571 0.000556 0.25409 0.04062 0.94792 0 3.47944 0.24790 2.15221 0.15331 0.88408 0.12651 0.54467 0.07794 55859.870543 0.000417 0.36487 0.06065 0.97222 0 3.23169 0.27777 1.95973 0.16843 1.17914 0.16777 0.71178 0.10125 55859.871399 0.000440 0.28031 0.04543 0.97368 0 3.94053 0.29977 2.39409 0.18213 1.10458 0.15807 0.66980 0.09584 55859.872291 0.000451 0.33694 0.05581 0.99359 0 3.15736 0.26797 1.91491 0.16244 1.06384 0.15134 0.64289 0.09145 55859.873193 0.000451 0.28851 0.04636 0.97436 0 3.82194 0.28979 2.30697 0.17492 1.10265 0.15620 0.66535 0.09425 55859.874061 0.000417 0.31404 0.05146 0.95833 0 3.76860 0.30102 2.30128 0.18378 1.18349 0.16935 0.71834 0.10279 55859.874788 0.000310 0.44435 0.07597 0.97196 0 3.60502 0.34627 2.15759 0.20724 1.60190 0.22656 0.96314 0.13621 55859.875447 0.000350 0.34388 0.05698 0.96694 0 4.11018 0.34328 2.45671 0.20517 1.41341 0.20227 0.84727 0.12124 55859.876133 0.000336 0.38061 0.06410 0.98276 0 3.89092 0.34399 2.30808 0.20405 1.48091 0.21226 0.87805 0.12583 55859.876903 0.000434 0.27283 0.04418 0.96000 0 4.13069 0.30675 2.50664 0.18613 1.12696 0.16219 0.68481 0.09857 55859.877658 0.000321 0.37470 0.06349 0.98198 0 3.96899 0.34933 2.40229 0.21143 1.48719 0.21535 0.89995 0.13031 55859.878327 0.000347 0.33253 0.05560 0.98333 0 4.11694 0.34435 2.50744 0.20972 1.36903 0.19822 0.83131 0.12037 55859.879247 0.000573 0.34616 0.04831 0.97980 0 3.51078 0.25057 2.13181 0.15214 1.21530 0.14575 0.73781 0.08847
