Class to transparently deal with the conversion between filters, wavelength,
|
|
frequency and other methods of specifying a location in the electro-magentic
|
|
spectrum.
|
|
|
|
Astro::WaveBand tries to determine the natural form of the numbers such that a
|
|
request for a summary of the object when it contains 2.2 microns would return
|
|
the filter name but would return the wavelength if it was not a standard filter.
|
|
In ambiguous cases an instrument name is required to decide what to return. In
|
|
really ambiguous cases the user can specify the unit in which to display the
|
|
numbers on stringification.
|
|
|
|
Used mainly as a way of storing a single number in a database table but using
|
|
logic to determine the number that an observer is most likely to understand.
|
|
|
|
Numerical comparison operators can be used to compare two Astro::WaveBand
|
|
objects. When checking equality, the "natural" and "instrument" methods are
|
|
used, so if two Astro::WaveBand objects return the same value from those
|
|
methods, they are considered to be equal. When checking other comparisons such
|
|
as greater than, the wavelength is used.
