/* ** ** 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 57955.883152 0.000318 0.11512 0.02715 0.95455 0 3.89080 0.29188 3.31004 0.24830 0.44789 0.10016 0.38159 0.08533 57955.883812 0.000341 0.11890 0.02816 0.99153 0 3.38265 0.26402 2.87756 0.22459 0.40219 0.08994 0.34245 0.07657 57955.884743 0.000590 0.17206 0.02653 0.98529 0 3.38845 0.20113 2.87761 0.17079 0.58300 0.08296 0.49563 0.07053 57955.885632 0.000298 0.11872 0.02850 0.98058 0 3.90967 0.30312 3.30705 0.25638 0.46416 0.10544 0.39131 0.08887 57955.886245 0.000315 0.11014 0.02599 0.98165 0 3.99091 0.30104 3.39905 0.25638 0.43956 0.09829 0.37446 0.08373 57955.887078 0.000518 0.13152 0.02426 0.98324 0 3.46510 0.21618 2.96082 0.18472 0.45573 0.07911 0.38911 0.06755 57955.887926 0.000330 0.10913 0.02611 0.98246 0 3.79653 0.28623 3.23522 0.24391 0.41431 0.09409 0.35288 0.08014 57955.888676 0.000420 0.09250 0.02141 0.96552 0 3.74341 0.25141 3.20673 0.21537 0.34626 0.07668 0.29661 0.06569 57955.889414 0.000318 0.11071 0.02609 0.97273 0 3.96900 0.29559 3.38283 0.25192 0.43942 0.09826 0.37446 0.08373 57955.890094 0.000362 0.09434 0.02207 0.99200 0 3.99314 0.27520 3.42364 0.23595 0.37670 0.08423 0.32312 0.07225 57955.891086 0.000631 0.14120 0.02173 0.97706 0 3.82954 0.20709 3.27406 0.17704 0.54074 0.07791 0.46260 0.06665 57955.892744 0.001027 0.14216 0.01692 0.98149 0 3.86913 0.16345 3.29698 0.13927 0.55002 0.06121 0.46835 0.05211 57956.274479 0.000440 0.11673 0.02762 0.97368 0 2.69662 0.20842 2.32454 0.17965 0.31477 0.07039 0.27072 0.06054 57956.275396 0.000477 0.10103 0.02405 0.96970 0 2.83605 0.20321 2.43793 0.17466 0.28653 0.06504 0.24710 0.05609 57956.276316 0.000443 0.18097 0.03726 0.95425 0 2.50018 0.20050 2.15336 0.17270 0.45247 0.08579 0.39065 0.07407 57956.277187 0.000428 0.13434 0.03247 0.97297 0 2.38893 0.19851 2.04707 0.17010 0.32093 0.07285 0.27455 0.06233 57956.278102 0.000486 0.11954 0.02867 0.93452 0 2.47066 0.19085 2.11031 0.16303 0.29535 0.06707 0.25182 0.05717 57956.278889 0.000301 0.16440 0.03973 0.97115 0 2.79981 0.25674 2.41221 0.22120 0.46030 0.10293 0.39670 0.08870 57956.279505 0.000315 0.14604 0.03541 0.95413 0 3.04104 0.25920 2.60829 0.22231 0.44410 0.10081 0.38015 0.08630 57956.280168 0.000347 0.19666 0.04501 0.96667 0 2.40293 0.22251 2.06574 0.19125 0.47256 0.09892 0.40532 0.08485
