1997A&AS..126..503M Scaleheights of 486 southern spiral galaxies and some statistical correlation. Ma J., Peng Q.-H., Chen R., Ji Z.-H., Tu C.-P. Received January 2; accepted April 15, 1997 Abstract. Based on Peng's method (1988), we obtain scaleheights of 486 southern spiral galaxies, the images of which are taken from the Digitized Sky Survey at Xinglong Station of Beijing Astronomical Observatory. The fitted spiral arms of 70 galaxies are compared with their images to get their optimum inclinations. The scaleheights of other 416 ones are listed in Table A1 in Appendix. After compiling and analyzing the data, we find some statistical correlations. The most interesting results are that a flatter galaxy is bluer and looks brighter, and galaxies become flatter along the Hubble sequence Sab - Scd. Key words: galaxies: fundamental parameters - galaxies: spiral - galaxies: structure
