    Dear Mamuro,
       I will ask Paranal to observe

    SuF02-017 if the conditions are clear - 10 hour integration

    SuF02-001 if the conditions are not clear (ie thin cirrus) - 3 hour
    integration

    SuF02-019 if the conditions are not clear - 3 hour integration.

    There is a bit of this cirrus at the moment.

    Cheers, Chris.
