getBand

Return to directory of Todd's CASA extensions

Converts a frequency to the ALMA band number. Calls parseFrequencyArgument if necessary. There is ambiguity in the overlap range of Band 2 and 3 (84-90 GHz). See also bandforspw, which does not have this ambiquity.

Usage:

au.getBand(freq)

• freq: can be a frequency in Hz, or a string with units at the end (GHz, MHz, kHz, or Hz)

Example:

CASA <2>: au.getBand('230GHz')
  Out[2]: 6
