Far-infrared line fluxes from the ISO LWS observations of Cas A.
Line	#1	#2	#3	#4	#5	#6	#7
FIR line fluxes F, 10^-11 erg/cm²/s
[O III] 52 $\mu$ m	5.4	9.3	5.4	<1.2	3.5	5.0	5.2
[O I] 63 $\mu$ m	<0.6	2.6	1.2	<1.2	1.0	1.0	0.9
[O III] 88 $\mu$ m	7.5	4.2	2.7	0.5	1.9	3.2	3.4
[O I] 145 $\mu$ m	<0.1	<0.09	0.3	0.1	<0.1	<0.1	<0.1
[O III] 4959 + 5007 Å line flux F, 10^-13 erg/cm²/s
	<0.1	25	2.0	<0.1	6.5	0.5	2.9

Fluxes from the matched regions in the HST ACS F475W filter are also given. The upper limits are at the 3 $\sigma$ level.
Note: ISO region positions are shown in Fig. 4. Regions #3, #6 and #7 have higher interstellar absorption column (Bieging & Crutcher 1986).
