| Abstract: | VLA observations at 6 cm have been obtained for three hydrogen-deficient objects (Upsilon Sgr, V 348 Sgr, and Abell 58). Abell 58 was also observed at 2 cm. Only upper limits to the flux density could be set for these sources. A new radio source at 6 cm was found in the field of Upsilon Sgr. The upper limit for 6-cm flux density of V 348 Sgr sets an upper limit to its reddening as E(B-V) = 0.65 or less. The hydrogen-deficient planetary nebula A 58 shows much lower radio flux than expected from the IR radio flux-density relationship of planetary nebulae. |
