/* ** ** 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 55837.151883 0.000457 0.15048 0.03706 0.96203 0 2.09542 0.18288 1.71974 0.15006 0.31531 0.07261 0.25673 0.05914 55837.152960 0.000619 0.12917 0.03072 0.97196 0 1.81321 0.14700 1.48952 0.12074 0.23422 0.05237 0.19263 0.04307 55837.154181 0.000602 0.11852 0.02806 0.97596 0 2.05839 0.15997 1.66095 0.12907 0.24397 0.05456 0.19737 0.04413 55837.155341 0.000558 0.13170 0.03183 0.97409 0 1.99545 0.16576 1.60242 0.13311 0.26280 0.05964 0.21035 0.04774 55837.156499 0.000599 0.11658 0.02756 0.98068 0 2.10472 0.16154 1.70388 0.13078 0.24536 0.05487 0.19737 0.04413 55837.157584 0.000486 0.12925 0.03078 0.98214 0 2.32517 0.19053 1.88111 0.15415 0.30053 0.06720 0.24283 0.05430 55837.158620 0.000550 0.12796 0.03009 0.96842 0 2.20401 0.17494 1.76968 0.14045 0.28203 0.06242 0.22581 0.04997 55837.159809 0.000639 0.11826 0.02801 0.97285 0 1.96659 0.15348 1.58184 0.12345 0.23258 0.05201 0.18636 0.04167 55837.161001 0.000553 0.13618 0.03296 0.98429 0 1.91638 0.16149 1.54038 0.12980 0.26096 0.05922 0.21035 0.04774 55837.162008 0.000454 0.17703 0.04307 0.99363 0 1.79714 0.17211 1.44944 0.13878 0.31815 0.07114 0.25684 0.05743 55837.163087 0.000625 0.10457 0.02495 0.97685 0 2.20690 0.16256 1.79166 0.13197 0.23077 0.05238 0.18742 0.04253 55837.164028 0.000315 0.22336 0.05547 0.97248 0 2.09430 0.22630 1.69133 0.18274 0.46778 0.10461 0.37799 0.08452 55837.165142 0.000799 0.11721 0.02430 0.95290 0 2.08667 0.14003 1.68853 0.11330 0.24458 0.04797 0.19805 0.03884
