/* ** ** 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 57551.281571 0.000229 0.20278 0.01618 1.00000 0 26.95071 0.87607 24.44694 0.79468 5.46515 0.39822 4.95736 0.36122 57551.282031 0.000231 0.19848 0.01540 1.00000 0 28.01921 0.89433 25.21331 0.80471 5.56117 0.39325 5.00834 0.35414 57551.282523 0.000260 0.17089 0.01326 1.00000 0 28.67790 0.85000 26.02189 0.77127 4.90081 0.35130 4.44692 0.31876 57551.283053 0.000269 0.15384 0.01174 0.98925 0 31.09032 0.86752 28.21898 0.78740 4.78290 0.33965 4.34104 0.30827 57551.283562 0.000240 0.19090 0.01496 1.00000 0 27.71958 0.87221 25.08299 0.78925 5.29175 0.37965 4.78924 0.34361 57551.284092 0.000289 0.16066 0.01244 0.97000 0 28.11501 0.79800 25.41563 0.72137 4.51683 0.32550 4.08471 0.29431 57551.284659 0.000278 0.15551 0.01202 0.98958 0 29.62033 0.83732 26.78991 0.75724 4.60629 0.33133 4.16320 0.29946 57551.285211 0.000275 0.16430 0.01278 1.00000 0 28.24862 0.82638 25.40026 0.74291 4.64113 0.33453 4.17070 0.30051 57551.285718 0.000231 0.18784 0.01459 1.00000 0 29.63318 0.91597 26.70607 0.82542 5.56618 0.39667 5.01002 0.35700 57551.286207 0.000258 0.17563 0.01354 0.97753 0 29.33036 0.86567 26.44456 0.78048 5.15122 0.36682 4.63813 0.33022 57551.286722 0.000258 0.16942 0.01312 0.98876 0 29.55999 0.87214 26.60697 0.78495 5.00815 0.35873 4.50903 0.32295 57551.287251 0.000272 0.16570 0.01289 0.98936 0 28.67606 0.83329 25.76143 0.74856 4.75168 0.34302 4.26805 0.30804 57551.287766 0.000243 0.18279 0.01412 1.00000 0 29.39555 0.89659 26.20161 0.79912 5.37313 0.38122 4.78681 0.33966 57551.288241 0.000231 0.18937 0.01497 1.00000 0 28.83200 0.90540 25.98139 0.81588 5.45999 0.39612 4.91153 0.35634 57551.288730 0.000258 0.17916 0.01386 1.00000 0 27.84263 0.84701 25.09790 0.76347 4.98823 0.35484 4.49538 0.31978 57551.289274 0.000286 0.18742 0.01361 0.99075 0 27.70754 0.80517 24.82579 0.72139 5.19298 0.34573 4.65093 0.30964
