[Fe/H] relations for c-type RR Lyrae Variables based upon Fourier Coefficients

Siobahn M. Morgan, Jennifer N. Wahl, Rachel M. Wieckhorst

[Fe/H] - phi_31 - log P relations are found for c-type RR Lyrae stars in globular clusters. The relations are analogous to that found by Jurcsik & Kovacs (1996) for field ab-type R…
