 [21.04D] Distances to M101, NGC 2403, and NGC 2366 via Long Period Variables   (Site not responding. Last check: 2007-10-17)
To verify the effectiveness of these RSV PL relations, the distances to the galaxies M101, NGC 2403, and NGC 2366 were determined.
The number of RSVs discovered in M101, NGC 2403, and NGC 2366 was 42, 61, and 20, respectively.
By assuming a distance modulus for the Large Magellanic Cloud of 18.5 ±0.1 mag, single epoch I-band photometry of the RSVs was used to construct random phase PL relations resulting in distance moduli for M101, NGC 2403, and NGC 2366 of 29.40 ±0.16, 27.67 ± 0.16, and 27.86 ±0.20 mag, respectively.
