Achievements

The wavelength calibration accuracy of LAMOST 2D pipeline is about 4.5km/s which is about 3% of resolution unit (2.5?), and our sky subtraction accuracy  is better than SDSS.


With measuring flux of fiber at 3 positions around bright stars, we have measured the accuracy of fiber positioner and adjust the system error of fiber positioners to within 1" .
