- Position: ra,dec of image center
- Size: NAXIS1, NAXIS2 in pixels, from FITS file
- Resolution: sqrt(BMAJ*BMIN), beam axial ratio BMAJ/BMIN of the lowest frequency plane (resolution varies with frequency, most users will convolve to the lowest resolution). Note that for narrow spw, CASA will place the BMAJ and BMIN keywords in the header, but for wide spectral windows they can be placed in a table attachment.
- start time: DATE-OBS from FITS file
- end time: DATE-END from FITS file
- minimum frequency
- maximum frequency
- spectral resolution (spectral channel width (Hz); CDELT3 in the FITS header)
- project
- polarization types: I
