Python API summary¶

from lsst.pipe.tasks.maskStreaks import MaskStreaksTask

classMaskStreaksTask(config: Optional[Config] = None, name: Optional[str] = None, parentTask: Optional[Task] = None, log: Optional[Union[logging.Logger, lsst.utils.logging.LsstLogAdapter]] = None): Find streaks or other straight lines in image data...

attributeconfig: Access configuration fields and retargetable subtasks.

methodrun(maskedImage): Find and mask streaks in a masked image...

Retargetable subtasks¶
