/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 55213.583534 0.000990 0.48937 0.04275 0.97368 0 4.11616 0.20670 2.44372 0.12257 2.01432 0.14400 1.19663 0.08541 55213.584833 0.000310 0.36348 0.06039 0.98131 0 4.59026 0.39413 2.61299 0.22435 1.66847 0.23734 0.94898 0.13500 55213.585443 0.000301 0.37161 0.06240 0.97115 0 4.70404 0.41324 2.64047 0.23195 1.74809 0.25016 0.98137 0.14045 55213.586676 0.000932 0.53463 0.04753 0.96584 0 4.21954 0.22139 2.37882 0.12478 2.25588 0.16191 1.27146 0.09125 55213.587946 0.000339 0.39709 0.06700 0.96581 0 4.02233 0.36472 2.21907 0.20120 1.59724 0.22725 0.88179 0.12545 55213.588609 0.000324 0.40477 0.06833 0.97321 0 4.13339 0.37380 2.27482 0.20568 1.67306 0.23847 0.92291 0.13152 55213.589260 0.000327 0.46425 0.08028 0.98230 0 3.44559 0.33856 1.93334 0.18994 1.59961 0.22763 0.89768 0.12771 55213.590634 0.001047 0.45910 0.04012 0.97514 0 4.34656 0.21369 2.43321 0.11960 1.99553 0.14415 1.11695 0.08068 55213.593071 0.001389 0.45657 0.03385 0.97103 0 4.47840 0.18560 2.57066 0.10650 2.04471 0.12568 1.17423 0.07215 55213.650226 0.001016 0.39445 0.03324 0.97436 0 4.02573 0.18041 2.94991 0.13217 1.58797 0.11335 1.16525 0.08316 55213.652124 0.000883 0.47051 0.04088 0.98033 0 3.87939 0.19187 2.82204 0.13957 1.82529 0.13040 1.32787 0.09487 55213.653991 0.000984 0.45610 0.03916 0.95882 0 3.68836 0.17562 2.67068 0.12716 1.68226 0.12019 1.21789 0.08701 55213.655924 0.000949 0.46283 0.04028 0.96951 0 3.69449 0.18020 2.67737 0.13058 1.70993 0.12324 1.23874 0.08929 55213.657807 0.000935 0.46034 0.03987 0.97523 0 3.76421 0.18353 2.73964 0.13358 1.73281 0.12403 1.26184 0.09032 55213.659922 0.001181 0.45002 0.03253 0.97794 0 4.28012 0.17130 3.12806 0.12519 1.92615 0.11596 1.40772 0.08475
