Proposal category

Proposals should be submitted for one of the six categories:

1.3MM:

Proposals that ask for 1.3mm data. 3mm receivers can be used for pointing and calibration purposes, but cannot provide any imaging.

2MM:

Proposals that ask for 2mm data. 3mm receivers can be used for pointing and calibration purposes, but cannot provide any imaging.

3MM:

Proposals that ask for 3mm data.

TIME FILLER:

Proposals that have to be considered as background projects to fill in periods where the atmospheric conditions do not allow mapping, to fill in gaps in the scheduling, or even to fill in periods when only a subset of the standard 6-antenna configurations will be available. These proposals will be carried out on a ``best effort'' basis only.

SPECIAL:

Exploratory proposals: proposals whose scientific interest justifies the attempt to use the PdB array beyond its guaranteed capabilities. This category includes for example non-standard frequencies for which the tuning cannot be guaranteed, non-standard configurations and more generally all non-standard observations. These proposals will be carried out on a ``best effort'' basis only.

LARGE PROGRAM:

This category is offered for the first time on both IRAM instruments. See Sect. Large Observing Programs for a detailed explanation.

The proposal category will have to be specified on the proposal cover sheet and should be carefully considered by proposers.
