/* ** ** 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 59371.451760 0.000324 0.27783 0.04323 0.97321 0 7.03149 0.51050 3.51919 0.25449 1.95357 0.26883 0.98745 0.13515 59371.452501 0.000417 0.24923 0.03388 0.96528 0 6.03423 0.36712 3.97777 0.24185 1.50393 0.18282 0.98657 0.11985 59371.453300 0.000382 0.18353 0.02882 0.96212 0 6.31509 0.39356 4.21305 0.26253 1.15903 0.16705 0.77577 0.11179 59371.454061 0.000379 0.26957 0.03810 0.98473 0 5.48837 0.36183 3.68773 0.24307 1.47949 0.18495 0.99390 0.12424 59371.454787 0.000347 0.20536 0.03240 0.98333 0 6.17914 0.40893 4.09031 0.27067 1.26893 0.18172 0.83958 0.12023 59371.455467 0.000327 0.21152 0.03310 0.94690 0 6.63414 0.43134 4.40337 0.28630 1.40325 0.19970 0.93101 0.13249 59371.456112 0.000318 0.23573 0.03786 0.99091 0 5.79565 0.41152 3.83444 0.27224 1.36618 0.19684 0.90387 0.13025 59371.456856 0.000425 0.16570 0.02537 0.97959 0 6.44054 0.37269 4.24374 0.24555 1.06719 0.15131 0.70190 0.09950 59371.457628 0.000347 0.21702 0.03438 0.98333 0 5.82802 0.39483 3.86980 0.26211 1.26480 0.18113 0.83958 0.12023 59371.458291 0.000315 0.20756 0.03354 0.99083 0 6.56037 0.44256 4.32200 0.29154 1.36164 0.19997 0.89702 0.13175 59371.458933 0.000327 0.21254 0.03427 0.95575 0 6.34424 0.42239 4.22201 0.28109 1.34843 0.19802 0.89702 0.13175 59371.459625 0.000365 0.24257 0.03541 0.96032 0 6.05330 0.38742 4.03287 0.25809 1.46837 0.19262 0.97980 0.12849 59371.460536 0.000547 0.23545 0.02863 0.98942 0 5.87609 0.31507 3.89399 0.20878 1.38352 0.15102 0.91738 0.10014
