Slit2Msa

class jwst.transforms.Slit2Msa(slits, models)

Bases: astropy.modeling.core.Model

Transform from Nirspec slit_frame to msa_frame.

Parameters

• slits (list) – A list of open slits. A slit is a namedtupe, Slit Slit(“name”, “shutter_id”, “dither_position”, “xcen”, “ycen”, “ymin”, “ymax”, “quadrant”, “source_id”, “shutter_state”, “source_name”, “source_alias”, “stellarity”, “source_xpos”, “source_ypos”, “source_ra”, “source_dec”)

• models (list) – List of models (Model) corresponding to the list of slits.
