fitsopen_generic(key: str, bucket: Bucket | str | None = None) -> fits.HDUList

Open an S3 object or local file as an HDUList. Note that unlike the ASDF and Parquet versions, this does not accept a blocksize argument. This is because it relies on astropy's FITS S3 behaviors, which are already somewhat 'smart'.

Parameters:

  • key (str) –

    path or S3 key

  • bucket (Bucket | str | None, default: None ) –

    Bucket object or bucket name if this is an S3 object; None if a local file

Returns: an HDUList object created from key
