MakeRawVisitInfoViaObsInfo¶
- class lsst.obs.base.MakeRawVisitInfoViaObsInfo(log=None, doStripHeader=False)¶
Bases:
object
Base class functor to make a VisitInfo from the FITS header of a raw image using
ObservationInfo
translators.Subclasses can be used if a specific
MetadataTranslator
translator should be used.The design philosophy is to make a best effort and log warnings of problems, rather than raising exceptions, in order to extract as much VisitInfo information as possible from a messy FITS header without the user needing to add a lot of error handling.
- Parameters:
- log
logging.Logger
or None Logger to use for messages. (None to use
Log.getLogger("lsst.obs.base.makeRawVisitInfoViaObsInfo")
).- doStripHeader
bool
, optional Strip header keywords from the metadata as they are used?
- log
