- jwst.cube_build.cube_build_wcs_util.find_corners_miri(input_data, this_channel, instrument_info, coord_system)[source]
Find the footprint of the MIRI channel data on the sky.
For a specific channel on an exposure, find the min and max of the spatial coordinates, either in
alpha,betaorra,decdepending on the type of cube being build; Also find the min and max of wavelength this channel covers.- Parameters:
- input_data
IFUImageModelor str Input model or file
- this_channelstr
Channel we are working with
- instrument_infodict
Dictionary holding x pixel min and max values for each channel
- coord_systemstr
Coordinate system of output cube: skyalign, ifualign, internal_cal
- input_data
- Returns:
- a_minfloat
Minimum value of coord 1 - along axis 1 of the IFU cube
- b1float
Coord 2 value corresponding to
a_min- a_maxfloat
Maximum value of coord 1 - along the axis 1 of the IFU cube
- b2float
Coord 2 value corresponding to
a_max- a1float
Coord 1 value coorsponding to
b_min- b_minfloat
Minimum value of coord 2 - along the axis 2 of the IFU cube
- a2float
Coord 1 value coorsponding to
b_max- b_maxfloat
Maximum value of coord 2 - along the axis 2 of the IFU cube
- lambda_minfloat
Minimum wavelength
- lambda_maxfloat
Maximum wavelength
