/* ** ** 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 57215.292684 0.000642 0.28809 0.04671 0.97748 0 1.87345 0.14564 1.59589 0.12405 0.53972 0.07680 0.45917 0.06532 57215.293781 0.000454 0.38447 0.06518 0.97452 0 1.95196 0.17467 1.67597 0.14997 0.75047 0.10806 0.64437 0.09278 57215.294710 0.000475 0.36568 0.06233 0.97561 0 1.95847 0.17590 1.67401 0.15034 0.71617 0.10376 0.61289 0.08878 57215.295514 0.000330 0.23162 0.05562 0.97368 0 1.97289 0.20646 1.69469 0.17734 0.45696 0.09876 0.39232 0.08479 57215.296891 0.001047 0.34914 0.04106 0.97616 0 1.88335 0.11468 1.61459 0.09830 0.65755 0.06615 0.56394 0.05673 57216.560847 0.000972 0.38010 0.04784 0.96781 0 2.17905 0.14794 1.46761 0.09909 0.82826 0.08779 0.56488 0.05952 57216.935687 0.000466 0.34751 0.05712 0.93789 0 2.26778 0.18688 1.90376 0.15685 0.78809 0.11209 0.66002 0.09387 57216.936506 0.000353 0.44351 0.07655 0.98361 0 2.21584 0.21667 1.87140 0.18294 0.98274 0.13977 0.83053 0.11812 57216.937189 0.000330 0.44926 0.07842 0.95614 0 2.34824 0.22634 1.99409 0.19220 1.05498 0.15352 0.89587 0.13037 57216.937909 0.000391 0.46378 0.08015 0.93333 0 2.00573 0.19451 1.69490 0.16436 0.93023 0.13305 0.78698 0.11257 57216.938598 0.000298 0.47263 0.08147 1.00000 0 2.49330 0.25058 2.10120 0.21119 1.17842 0.16502 0.99194 0.13890 57216.939318 0.000422 0.38420 0.06568 0.97260 0 2.11818 0.19288 1.79912 0.16383 0.81381 0.11775 0.69122 0.10001 57216.940175 0.000434 0.37962 0.06361 0.98000 0 2.11363 0.18991 1.79505 0.16128 0.80238 0.11347 0.68141 0.09637 57216.940976 0.000362 0.45518 0.07856 0.98400 0 2.08534 0.20141 1.77114 0.17107 0.94920 0.13577 0.80618 0.11531 57216.941821 0.000483 0.31593 0.05224 0.97006 0 2.27818 0.18570 1.92761 0.15712 0.71974 0.10354 0.60899 0.08761 57216.942785 0.000480 0.32693 0.05370 0.95181 0 2.26558 0.18287 1.91718 0.15473 0.74069 0.10595 0.62759 0.08977 57216.943823 0.000558 0.30606 0.04921 0.97927 0 2.07891 0.16420 1.76622 0.13950 0.63628 0.08910 0.54058 0.07570 57216.944764 0.000382 0.39849 0.06696 0.96970 0 2.31182 0.20980 1.96370 0.17821 0.92124 0.13028 0.78255 0.11067 57216.945568 0.000422 0.33481 0.05543 0.97945 0 2.45820 0.20492 2.07019 0.17254 0.82302 0.11771 0.69343 0.09919 57216.946407 0.000417 0.38810 0.06562 0.97222 0 2.14250 0.19039 1.81277 0.16109 0.83150 0.11962 0.70469 0.10138 57216.947278 0.000454 0.40985 0.06897 0.96815 0 1.89519 0.17289 1.60456 0.14636 0.77674 0.10985 0.65899 0.09320 57216.948129 0.000396 0.42988 0.07238 0.98540 0 2.09047 0.19542 1.75647 0.16420 0.89865 0.12584 0.75681 0.10598 57216.949246 0.000720 0.36081 0.04514 0.96787 0 2.38257 0.15332 2.01747 0.12982 0.85965 0.09224 0.72733 0.07803
