/* ** ** 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 56545.879740 0.000773 0.10164 0.02456 0.95506 0 1.80283 0.13083 1.50503 0.10922 0.18324 0.04223 0.15297 0.03526 56545.881297 0.000784 0.11106 0.02621 0.97048 0 1.64316 0.12401 1.37174 0.10352 0.18249 0.04081 0.15234 0.03407 56545.883033 0.000952 0.09387 0.02143 0.96657 0 1.68823 0.11334 1.40936 0.09462 0.15847 0.03458 0.13230 0.02887 56545.884827 0.000842 0.09669 0.02266 0.98625 0 1.72960 0.12127 1.44390 0.10124 0.16723 0.03739 0.13961 0.03122 56545.886636 0.000966 0.07920 0.01840 0.97605 0 1.85899 0.11746 1.55192 0.09806 0.14722 0.03292 0.12290 0.02748 56545.888375 0.000773 0.09323 0.02183 0.98502 0 1.95731 0.13616 1.63400 0.11367 0.18249 0.04081 0.15234 0.03407 56545.890415 0.001267 0.10701 0.01907 0.98142 0 1.82598 0.10299 1.52436 0.08598 0.19539 0.03303 0.16311 0.02757 56545.946470 0.000613 0.12785 0.03041 0.98113 0 1.77894 0.14428 1.50669 0.12220 0.22743 0.05086 0.19263 0.04307 56545.947749 0.000666 0.13593 0.03207 0.96522 0 1.62452 0.13201 1.37591 0.11180 0.22082 0.04891 0.18703 0.04143 56545.948996 0.000582 0.13865 0.03229 0.96517 0 1.84671 0.15025 1.56409 0.12726 0.25604 0.05587 0.21686 0.04732 56545.950287 0.000709 0.12618 0.02997 0.97959 0 1.56208 0.12501 1.32302 0.10588 0.19711 0.04408 0.16694 0.03733 56545.951936 0.000940 0.09162 0.02206 0.98154 0 1.57415 0.10814 1.33324 0.09159 0.14423 0.03328 0.12216 0.02819 56545.953979 0.001102 0.07942 0.01846 0.97113 0 1.60996 0.10257 1.36358 0.08687 0.12786 0.02859 0.10829 0.02421 56545.956716 0.001635 0.10367 0.01745 0.96536 0 1.63143 0.08462 1.38176 0.07167 0.16913 0.02708 0.14325 0.02294 56545.998549 0.000697 0.11660 0.04444 0.88797 0 1.27082 0.16324 0.63336 0.08136 0.14818 0.05317 0.07385 0.02650
