Add Metadata
The Add Metadata command changes Changes (adds, replaces, and renames) keyword metadata when the image is opened or is saved to a FITS format file. Among its many applications, this command is useful for including static keywords not added by the camera control software, such as SITELONG, SITELAT, RDNOISE, and GAIN, AUTHOR, etc., or renaming misnamed FITS keywords such as changing EXPOSURE to EXPTIME.
The Add Metadata command configures metadata changes but does not them to an image. The metadata are applied when the file is opened or is saved to a FITS file. The option for applying metadata changes at open or save is configuring using checkboxes in the General Properties (Ctrl+R) dialog. The state of these checkboxes is shown in the Add Metadata dialog. They cannot be changed from the Add Metadata dialog.
This command is closely related to the Modify Keywords command which changes metadata of an open image.
