what to do when gaps are detected, one of
- `ignore` : do nothing
- `warn` : display the existence of gaps but carry on
- `raise` : raise an exception
onerror : `str`, optional
what to do when the `~glue.datafind` query itself fails, same
options as for ``gaps``
Returns
-------
cache : `~glue.lal.Cache`
