/* ** ** 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 57784.175742 0.000712 0.26306 0.02198 0.96748 0 17.40208 0.65885 6.17204 0.23333 4.57787 0.34089 1.61775 0.12024 57784.177104 0.000651 0.30470 0.02564 0.96444 0 17.10314 0.68848 5.86640 0.23615 5.21136 0.38503 1.78835 0.13212 57784.178441 0.000686 0.31050 0.02585 0.96624 0 16.07170 0.64728 5.50039 0.22153 4.99028 0.36357 1.70865 0.12447 57784.179769 0.000642 0.28335 0.02312 0.96396 0 19.14399 0.72932 6.51795 0.24829 5.42447 0.39149 1.84753 0.13335 57784.181106 0.000694 0.28367 0.02354 0.95833 0 17.47453 0.67077 5.94890 0.22836 4.95693 0.36474 1.68762 0.12418 57784.182460 0.000660 0.29193 0.02398 0.97368 0 17.83595 0.70112 6.08022 0.23901 5.20688 0.37557 1.77662 0.12814 57784.183771 0.000651 0.30492 0.02545 0.99556 0 16.85400 0.68686 5.72303 0.23313 5.13913 0.37439 1.74679 0.12725 57784.185047 0.000625 0.31199 0.02604 0.97222 0 17.60014 0.71608 5.98826 0.24361 5.49103 0.40019 1.86782 0.13616 57784.186913 0.001241 0.28199 0.01722 0.97203 0 17.75332 0.50872 5.99941 0.17190 5.00621 0.27004 1.69238 0.09128
