fixvframe

procedure fixvframe, buffer=variable, [newframe=string]

Adjust the frame_velocity value in the primary data container (PDC, buffer 0) using the external CASA library.

Other buffers can be adjusted using the buffer keyword.

Note that the first time this function is called there will be a small delay while the shared library is loaded. Subsequent calls will be substantially faster.

Examples: ; adjust the frame velcity in the PDC fixvframe ; adjust it to the GAL (galactic) frame dcfixvframe,newframe='GAL' ; adjust it in the data in buffer 2 fixvframe,buffer=2
Uses: dcfixframe, data_copy, set_data_container

Keywords

buffer
in/out, required
variable (def. 0) The data buffer to use. This defaults to the primary data container (buffer 0). The value of the frame_velocity in this buffer is changed by calling this procedure.

newframe
in, optional
string The new reference frame to use. If not supplied, the frame implied by the velocity_definition in this buffer will be used. This string must be one of TOPO, GEO, HEL, BAR, LSR, LSD, and GAL. If this is set, then the velocity_definition will be changed to match this keyword.
