Description

Runs a query in the SDSS database that searches for all objects within a certain radius from a point in the sky, and retrieves the result table as a dataframe. Maximum number of rows retrieved is set currently to 500,000.

Usage

Arguments

ra	Right Ascension of the point in the sky.
dec	Declination of the point in the sky.
radius	Search radius around the (ra,dec) coordinate in the sky. Measured in arcminutes.
coordType	Type of celestial coordinate system. Can be set to "equatorial" or "galactic".
