during processing. In case a scene is suspected to be missing, the Alaska Satellite Facility (ASF)
online catalog is cross-checked.
An error will only be raised if the locally missing scene is present in the ASF catalog.
It may happen that a neighbor is missing and this error is not raised if the scene is also
missing on ASF.
