Revised elements for DT Cygni.

RHODE K.L.

Abstract (from CDS):

Recent observations of the s-Cepheid DT Cygni and published data were used to revise the elements for this star. An interpretation of the period changes of DT Cygni suggested by Szabados is not supported. Another interpretation of the period behavior is supported.
