This is to replicate the LEL (lattice expression language) support of the file browser in casaviewer. Users can enter an expression in a text field so that a new image can be formed dynamically. The relevant backend issue is: CARTAvis/carta-backend#665

Screenshot of viewer file browser, to load image aJ.fits with values squared. "LEL expression" text input only appears when LEL checkbox is checked.
