The VLA Resources section allows you to create, edit, and remove resources appropriate to the VLA,
specifying such information as the array configuration, observing frequency, frequency resolution, and
number of channels. You must create a separate resource for every different combination of these
attributes. Click on the ``Add'' button to add a resource. Details about how to make these choices may
be found in the VLA Observational Status Summary:

4.5.4 Miscellaneous VLA Resources Issues
Simultaneous Receivers:
While normally one may use only a single receiver at a time on the VLA, one may observe
simultaneously in both 4 and P bands (4P mode) or in both L and P bands (LP mode). Such
receiver modes cannot be specified as a single VLA resource. Instead, two resources must be
created (e.g., these could be called LP-Lband and LP-Pband). When creating sessions that use
these resources only select one resource (e.g., LP-Lband) for the relevant source/resource pair.
This is necessary to get the correct total integration time. Then note in the comments field that
you are using multiple resources and specify the relevant resource name (e.g., ``The
source/resource pair Abell 1914/LP-Lband is using the LP mode. See resource LP-Pband
band.'').
NOTE: Given the EVLA-VLA transition, users who are requesting LP mode should consult the
staff for technical advice.
Subarrays:
You must create separate resources for each subarray. When creating sessions that use these
resources use the ``Add Subarray'' link to specify the different subarrays. Additional
information should be included in the comments field. For example, ``Resource Sub-1 will use
