The VLA observations presented by Pottasch et al. (1988, A&A 205, 248) and Ratag et al. (1990, A&A 233, 181) demonstrate that IRE (Pottasch et al. 1984, A&A 138, 10) correlates very well with F(6 cm) for the Galactic center PN, especially when IRE is large The correlation (see figure) can be approximated by:
