/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 57320.862465 0.000842 0.13382 0.03100 0.94828 1 4.51888 0.35137 1.14669 0.08915 0.60473 0.13197 0.15273 0.03333 57320.864194 0.000886 0.12449 0.02945 0.93443 1 4.44097 0.34285 1.12652 0.08696 0.55284 0.12363 0.14035 0.03138 57320.866213 0.001133 0.18357 0.03253 0.97164 1 4.27328 0.29835 1.08761 0.07593 0.78446 0.12779 0.19979 0.03254 57321.853764 0.000523 0.28528 0.05602 0.97222 1 5.31057 0.49205 1.34661 0.12476 1.51502 0.26228 0.38522 0.06668 57321.854809 0.000523 0.18306 0.04514 0.94444 1 5.02746 0.48117 1.26493 0.12105 0.92033 0.20913 0.23185 0.05267 57321.856000 0.000668 0.12602 0.03029 0.93478 1 5.82807 0.45715 1.46123 0.11461 0.73447 0.16685 0.18332 0.04165 57321.857061 0.000392 0.21494 0.05418 1.00000 1 5.41037 0.59102 1.35959 0.14851 1.16289 0.26419 0.29196 0.06633 57321.857990 0.000537 0.14902 0.03581 1.00000 1 5.88005 0.51735 1.45202 0.12775 0.87623 0.19594 0.21622 0.04835 57321.858920 0.000392 0.22453 0.05582 1.00000 1 5.33275 0.57910 1.32268 0.14362 1.19737 0.26775 0.29630 0.06625 57321.859733 0.000421 0.16364 0.03949 0.96552 1 7.05704 0.64041 1.74668 0.15851 1.15481 0.25823 0.28572 0.06389 57321.860634 0.000479 0.16602 0.04031 0.93939 1 6.25778 0.56554 1.54085 0.13926 1.03892 0.23414 0.25617 0.05774 57321.861506 0.000392 0.22910 0.05745 1.00000 1 5.21138 0.57290 1.28329 0.14108 1.19391 0.26910 0.29413 0.06629 57321.862246 0.000349 0.25717 0.06585 1.00000 1 5.12801 0.60627 1.27632 0.15085 1.31878 0.29955 0.32845 0.07462 57321.862944 0.000349 0.25470 0.06507 1.00000 1 5.23018 0.61164 1.28906 0.15074 1.33213 0.30260 0.32845 0.07462 57321.863931 0.000639 0.21789 0.04228 0.96447 1 5.72796 0.48114 1.42414 0.11962 1.24808 0.21834 0.30967 0.05416
