GCO Observations of Neutral Hydrogen in the Magellanic Clouds
Joachim Köppen Kiel Jan.2018


Some brief explanations

This tool shows the results of a survey of the Southern Hemisphere skies in the radio line of atomic hydrogen at 21 cm wavelength, done with the 2.3m diameter SRT at Grove Creek Observatory. With a system temperature near 170 K, the integration times are 5 or 10 min on each position.

Test operations in 2018 were done with a system temperature of about 500 K. Integration times were increased to 2 hours per position.

The results are shown as:
