/* ** ** 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 56811.147361 0.000613 0.07776 0.01789 0.98585 0 3.00677 0.18687 2.53455 0.15753 0.23382 0.05179 0.19865 0.04400 56811.148623 0.000648 0.08958 0.02158 0.97768 0 2.33791 0.16039 1.97906 0.13576 0.20942 0.04835 0.17792 0.04106 56811.149682 0.000411 0.13082 0.03211 0.97183 0 2.55034 0.21238 2.16379 0.18018 0.33364 0.07702 0.28235 0.06517 56811.150521 0.000428 0.11030 0.02683 0.98649 0 2.84440 0.21802 2.41449 0.18504 0.31374 0.07244 0.26688 0.06160 56811.151632 0.000683 0.07338 0.01751 0.96186 0 2.77219 0.16825 2.34639 0.14240 0.20342 0.04695 0.17165 0.03962 56811.152792 0.000477 0.12266 0.02909 0.98788 0 2.38629 0.18864 2.00086 0.15816 0.29271 0.06546 0.24581 0.05496 56811.153733 0.000463 0.10201 0.02472 0.98125 0 2.88718 0.21314 2.42101 0.17872 0.29452 0.06798 0.24818 0.05728 56811.154803 0.000608 0.08614 0.02012 0.99524 0 2.63303 0.17717 2.22462 0.14966 0.22680 0.05072 0.19171 0.04287 56811.155897 0.000486 0.08929 0.02119 0.98214 0 3.14903 0.21514 2.67543 0.18278 0.28116 0.06389 0.23949 0.05440 56811.157014 0.000631 0.08913 0.02081 0.97248 0 2.53044 0.17027 2.11370 0.14222 0.22554 0.05044 0.18899 0.04226 56811.158267 0.000622 0.08897 0.02077 0.96744 0 2.61657 0.17560 2.16513 0.14531 0.23279 0.05205 0.19263 0.04307 56811.159297 0.000408 0.14776 0.03174 0.97872 0 2.96907 0.23297 2.45629 0.19273 0.43870 0.08774 0.36292 0.07258
