This is based on a list of known sky-lines built into CWITools, which is currently a work in progress. It is not an exhaustive list by any means.

Parameters:

• inst (str) – ‘KCWI’ or ‘PCWI’ - to determine whether Keck or Palomar sky is requested.
• use_vacuum (bool) – Set to True to convert the sky lines to vacuum wavelengths.

Returns:

An array of the sky lines in units of Angstrom.

Return type:
