Advanced Large, Homogeneous Area Medium Band Redshift Astronomical Survey[1]
- 20个中带（300A)波段,3500-9700A
- 3个近红外波段J,H,K
- 8个天区 北天(和一些知名天区有重合，如DEEP2，COSMOS，GOODS-N,AEGIS)，每个天区约0.3平方度，共2.4平方度，48个子天区
- 望远镜：3.5 m de Calar Alto 西班牙
- CCD，0.22arcsec/pixel
magnitude limits (for a total of 100 ks integration time per pointing) of AB <= 25 mag (for anunresolved object, signal-to-noise ratio = 5) in the optical filtersfrom the blue to 8300 Å, and from AB = 24.7 to 23.4 for the redderones. The limit in the NIR, for a total of 15 ks exposure time perpointing, is (in the Vega system) Ks ≈ 20 mag, H≈ 21mag, J≈ 22 mag.
