Galaxy: Radial Velocity of Galaxy NGC7531

Description

This data set is a record of radial velocity of a spiral galaxy that is measured at 323 points in its covered area of the sky. The positions of the measurements, that are in the range of seven slot crossing at the origin, are denoted by 4 variables.

Usage

data(Galaxy)

Format

A data frame with 324 observations recorded on the following 5 variables.

east.west

It is the east-west coordinate where east is taken as negative, west is taken as positive and origin, (0,0), is close to the center of galaxy.

north.south

It is the north-south coordinate where south is taken as negative, north is taken as positive and origin, (0,0), is near the center of galaxy.

angle

It is the degrees of anti rotation (clockwise) from the slot horizon where the observation lies.

radial.position

It is the signed distance from the center, (0,0), which is signed as negative if the east-west coordinate is negative.

velocity

This is the response variable denoting the radial velocity(km/sec) of the galaxy.
