Spectral filter handling

This class only has static functions to read and list the available filters

There are a number of filters available from the ICR which can be retrieved directly by the name. The name prefixes may be omitted as long as the name remains unique.

The list of filters includes:

• GAIA2r.Gbp, GAIA2r.G, GAIA2r.Grp

• CTIO DECam.g, DECam.i, DECam.r, DECam.u, DECam.z

• Generic Bessell.U, Cousins.I, Cousins.R, Johnson.B, Johnson.V

• Paranal VISTA.H, VISTA.J, VISTA.Ks, VISTA.Y, VISTA.Z

The complete list of filters can be retrieved with the list() function.

User defined filters can be used by providing a file name instead. Note that SDSS filters are not in the list of standard filters and need to be provided as file name.
