Integrated flux densities of NGC 891 and 4565 contained in the various total intensity images.

	NGC 891	NGC 4565 ^(a)
L-band B-array	322 ± 16	31.8 ± 1.6
L-band C-array	560 ± 28	73.7 ± 3.7
L-band B+C+D-array	695 ± 35	135 ± 7

Non-thermal (6 GHz) ^(b)	206 ± 34	27 ± 9

Notes. All values are given in mJy.

^(a)

Flux densities of NGC 4565 were determined after subtracting the central source of the galaxy from the VLA images.

^(b)

For each galaxy, to obtain the non-thermal map at 1.5 GHz, the thermal map was subtracted from the combination of the L-band D-array and B+C+D-array maps. At 6 GHz, the thermal map was subtracted from the combination of the C-band D-array and Effelsberg maps.
