I note that "Z" plays an important role in what the ALFA surveys will look for:
HI rich objects | few metals | low Z |
nearby low mass | low redshift | low z |
Arecibo | low zenith angle | Low Z |
Riccardo | Don't you have a bias at low MHI so that you don't detect many? |
Steve | This is an HI selected sample. |
Steve | The same effect is seen in optical surveys because of the small volume. |
