/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 60109.185823 0.000373 0.21821 0.01741 1.00000 0 17.21911 0.57900 14.06942 0.47287 3.75745 0.27188 3.07989 0.22256 60109.186555 0.000359 0.21035 0.01667 0.97581 0 18.99112 0.62026 15.49970 0.50616 3.99480 0.28834 3.26563 0.23562 60109.187267 0.000353 0.21750 0.01738 0.99180 0 18.71419 0.63087 15.02151 0.50640 4.07031 0.29492 3.26696 0.23670 60109.187964 0.000344 0.21385 0.01691 0.99160 0 19.46311 0.64567 15.80677 0.52438 4.16221 0.29879 3.38261 0.24280 60109.188702 0.000394 0.18420 0.01455 0.99265 0 19.54255 0.60755 15.81076 0.49155 3.59978 0.26149 2.91333 0.21163 60109.189474 0.000379 0.19945 0.01591 0.99237 0 18.71305 0.59982 15.26858 0.48937 3.73229 0.27266 3.04327 0.22229 60109.190206 0.000353 0.20578 0.01650 0.99180 0 19.32786 0.63649 15.75133 0.51866 3.97722 0.29077 3.23518 0.23661 60109.190921 0.000362 0.22231 0.01781 0.99200 0 17.54542 0.59892 14.33627 0.48933 3.90048 0.28268 3.18792 0.23097 60109.191642 0.000359 0.20210 0.01598 0.99194 0 19.36311 0.62642 15.87824 0.51358 3.91335 0.28241 3.21253 0.23179 60109.192336 0.000336 0.22618 0.01824 0.98276 0 18.65657 0.64097 15.26662 0.52446 4.21967 0.30782 3.45141 0.25175 60109.193054 0.000382 0.18593 0.01509 1.00000 0 19.27890 0.61305 15.75039 0.50077 3.58451 0.26757 2.92372 0.21823 60109.193803 0.000367 0.19992 0.01567 0.97638 0 19.78235 0.62913 16.02487 0.50960 3.95491 0.28339 3.20148 0.22944 60109.194495 0.000324 0.22381 0.01810 1.00000 0 19.38403 0.66960 15.61678 0.53949 4.33840 0.31724 3.49515 0.25562 60109.195201 0.000382 0.19528 0.01514 0.99242 0 19.55406 0.61715 15.72278 0.49621 3.81848 0.27046 3.07505 0.21780 60109.195985 0.000402 0.18609 0.01480 0.99281 0 18.70518 0.58471 15.23127 0.47612 3.48090 0.25455 2.83665 0.20746 60109.196795 0.000408 0.19356 0.01457 0.98582 0 19.80827 0.60402 16.07326 0.49002 3.83400 0.26387 3.11658 0.21452
