/* ** ** 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 55803.296573 0.000367 0.30852 0.05044 0.98425 0 2.97866 0.23547 2.57070 0.20321 0.91898 0.13152 0.79290 0.11348 55803.297314 0.000373 0.28074 0.04523 0.96899 0 3.27168 0.24741 2.83926 0.21471 0.91851 0.13067 0.79712 0.11340 55803.298078 0.000391 0.29427 0.04743 0.96296 0 3.02886 0.23418 2.61813 0.20243 0.89130 0.12605 0.77051 0.10897 55803.298949 0.000480 0.23352 0.03637 0.98795 0 3.07119 0.20953 2.66896 0.18208 0.71717 0.10042 0.62299 0.08724 55803.299849 0.000420 0.27114 0.04350 0.97241 0 2.99897 0.22249 2.60479 0.19325 0.81315 0.11568 0.70666 0.10054 55803.300743 0.000475 0.21673 0.03420 0.97561 0 3.33368 0.22151 2.86322 0.19025 0.72252 0.10341 0.61945 0.08866 55803.301611 0.000394 0.25405 0.04035 0.97794 0 3.41040 0.24659 2.96517 0.21440 0.86640 0.12253 0.75313 0.10651 55803.302349 0.000344 0.36863 0.05664 0.98319 0 3.10470 0.24775 2.69405 0.21498 1.14449 0.15028 0.99311 0.13040 55803.303075 0.000382 0.28790 0.04675 0.96970 0 3.10598 0.23814 2.69237 0.20643 0.89420 0.12799 0.77432 0.11082 55803.303926 0.000469 0.20848 0.03281 0.96914 0 3.49737 0.22898 3.03154 0.19846 0.72914 0.10435 0.63129 0.09035 55803.304858 0.000463 0.21967 0.03498 0.98125 0 3.33317 0.22661 2.86944 0.19509 0.73221 0.10543 0.62793 0.09041 55803.305697 0.000376 0.28249 0.04546 0.99231 0 3.19559 0.24548 2.74731 0.21105 0.90271 0.12767 0.77649 0.10981 55803.306382 0.000310 0.36939 0.06245 0.98131 0 2.92644 0.25921 2.54190 0.22515 1.08101 0.15565 0.93891 0.13519 55803.307031 0.000339 0.34174 0.05638 0.98291 0 2.95497 0.24675 2.53328 0.21151 1.00984 0.14367 0.86643 0.12327 55803.308176 0.000807 0.26594 0.03059 0.97491 0 3.11411 0.16448 2.67682 0.14138 0.82817 0.08461 0.71055 0.07259
