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

Usage

SkyServer.rectangularSearch(min_ra, max_ra, min_dec, max_dec, coordType="equatorial", whichPhotometry="optical", limit="0", dataRelease=NULL)

Arguments

min_ra	Minimum value of Right Ascension coordinate that defines the box boundaries on the sky.
max_ra	Maximum value of Right Ascension coordinate that defines the box boundaries on the sky.
min_dec	Minimum value of Declination coordinate that defines the box boundaries on the sky.
max_dec	Maximum value of Declination coordinate that defines the box boundaries on the sky.
coordType	Type of celestial coordinate system. Can be set to "equatorial" or "galactic".
whichPhotometry	Type of retrieved data. Can be set to "optical" or "infrared".
