The cepheid period-luminosity in the near-infrared

The Cepheid period-luminosity relations in the J- and K-bands, as obtained from the current VLT data on NGC 300. The mean magnitudes for each Cepheid were determined from two independent measurements of Cepheid brightness at different pulsation phases. The slopes of the best-fitting relations were adopted from the Large Magellanic Cloud Cepheids.
