def lsst.obs.base.utils.createInitialSkyWcs | ( | visitInfo, | |

flipX = False |
|||
) |
Create a SkyWcs from the visit information and detector geometry. A typical usecase for this is to create the initial WCS for a newly-read raw exposure. Parameters ---------- visitInfo : `lsst.afw.image.VisitInfo` Where to get the telescope boresight and rotator angle from. detector : `lsst.afw.cameraGeom.Detector` Where to get the camera geomtry from. flipX : `bool`, optional If False, +X is along W, if True +X is along E. Returns ------- skyWcs : `lsst.afw.geom.SkyWcs` The new composed WCS. Raises ------ InitialSkyWcsError Raised if there is an error generating the SkyWcs, chained from the lower-level exception if available.

def lsst.obs.base.utils.createInitialSkyWcsFromBoresight | ( | boresight, | |
orientation, | |||
detector, | |||
flipX = False |

) |
Create a SkyWcs from the telescope boresight and detector geometry. A typical usecase for this is to create the initial WCS for a newly-read raw exposure. Parameters ---------- boresight : `lsst.geom.SpherePoint` The ICRS boresight RA/Dec orientation : `lsst.geom.Angle` The rotation angle of the focal plane on the sky. detector : `lsst.afw.cameraGeom.Detector` Where to get the camera geomtry from. flipX : `bool`, optional If False, +X is along W, if True +X is along E. Returns ------- skyWcs : `lsst.afw.geom.SkyWcs` The new composed WCS. Raises ------ InitialSkyWcsError Raised if there is an error generating the SkyWcs, chained from the lower-level exception if available.

def lsst.obs.base.utils.getInstrument | ( | instrumentName, | |
registry = None |
|||
) |
Return an instance of a named instrument. If the instrument name not is qualified (does not contain a '.') and a butler registry is provided, this will attempt to load the instrument using Instrument.fromName. Otherwise the instrument will be imported and instantiated. Parameters ---------- instrumentName : string The name or fully-qualified class name of an instrument. registry : `lsst.daf.butler.Registry`, optional Butler registry to query to find information about the instrument, by default None Returns ------- Instrument subclass instance The instantiated instrument. Raises ------ RuntimeError If the instrument can not be imported, instantiated, or obtained from the registry. TypeError If the instrument is not a subclass of lsst.obs.base.Instrument.
def lsst.obs.base.utils.setDottedAttr | ( | item, | |
name, | |||
value | |||
) |
Set an instance attribute (like `setattr` but accepting hierarchical names such as ``foo.bar.baz``) If the attribute can not be set as a string, will attempt to set the attribute with the result of eval'ing the value. Parameters ---------- item : obj Object whose attribute is to be set. name : `str` Name of attribute to set. value : obj New value for the attribute. Notes ----- For example if name is ``foo.bar.baz`` then ``item.foo.bar.baz`` is set to the specified value. Raises ------ AttributeError If the item does not have a field specified by name that can be set. RuntimeError If the value can not be set as a string or rendered by eval, or if there is an error setting the attribute with the rendered value.
