(
Arp 224 =
UGC 6823)
John Hibbard, NRAO
The HI data were obtained at the VLA in 1/91 & 5/91.
The Halpha and R-band data were obtained with the KPNO 2.1m in 3/92.
UBVR data taken with the KPNO Burrel-Schmidt in 2/91
The K-band data were obtained with the UH88" in 1/95.
CO data were obtained from OVRO with Min Yun in 12/94.
