摘要：

We have identified four Cepheids and five Miras using KPNO 4 m BVRI CCD images of an outer field in M101. The Cepheid and Mira periods range from 30 to 60 days and 350 to 800 days, respectively. We derive independent Cepheid and Mira distance moduli that agree within experimental uncertainties. We find a true distance modulus of 29.08±0.13 mag. © 1995 American Astronomical Society.
