/* ** ** 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 57948.312270 0.000472 0.17928 0.02780 0.96319 0 4.14688 0.24750 3.52849 0.21058 0.74347 0.10640 0.63132 0.09035 57948.313436 0.000694 0.12286 0.01844 0.97083 0 4.17142 0.20697 3.53717 0.17551 0.51249 0.07261 0.43399 0.06148 57948.314576 0.000446 0.22814 0.03579 0.97403 0 3.45103 0.23444 2.93344 0.19927 0.78732 0.11135 0.66778 0.09444 57948.315621 0.000599 0.15040 0.02294 0.97101 0 3.86395 0.21270 3.29515 0.18139 0.58113 0.08267 0.49573 0.07052 57948.316787 0.000567 0.13920 0.02138 0.97449 0 4.37944 0.23458 3.71097 0.19876 0.60961 0.08777 0.51619 0.07432 57948.317855 0.000501 0.18132 0.02807 0.97688 0 3.80448 0.23224 3.25058 0.19843 0.68985 0.09814 0.58960 0.08388 57948.318870 0.000515 0.17907 0.02769 0.98315 0 3.73826 0.22669 3.17604 0.19260 0.66942 0.09524 0.56938 0.08100 57948.319770 0.000385 0.11352 0.02565 0.96405 0 3.69871 0.26070 3.16121 0.22281 0.41988 0.09013 0.35861 0.07698 57948.378927 0.000466 0.17115 0.02620 0.96273 0 4.41295 0.25822 3.77575 0.22094 0.75528 0.10682 0.64624 0.09139 57948.380035 0.000642 0.13862 0.02103 0.98198 0 3.89264 0.20556 3.29786 0.17415 0.53959 0.07676 0.45711 0.06502 57948.381242 0.000564 0.15158 0.02368 0.96923 0 4.03875 0.22812 3.40293 0.19220 0.61221 0.08917 0.51630 0.07520 57948.382353 0.000547 0.15995 0.02501 0.96296 0 3.90142 0.22192 3.35213 0.19068 0.62403 0.09089 0.53616 0.07809 57948.383472 0.000573 0.08092 0.01690 0.95956 0 4.00745 0.22442 3.37962 0.18925 0.32429 0.06525 0.27381 0.05506 57949.375331 0.000362 0.13689 0.03317 0.96000 0 2.82620 0.23871 2.39720 0.20246 0.38687 0.08786 0.32943 0.07479 57949.376009 0.000315 0.18604 0.04585 0.94495 0 2.40987 0.23085 2.05278 0.19662 0.44833 0.10180 0.38381 0.08714 57949.377290 0.000966 0.08359 0.01578 0.96707 0 2.71368 0.14232 2.28407 0.11979 0.22683 0.04113 0.19062 0.03457
