For a total of 60 infrared sources optical depths of the 10‐μm absorption band and temperatures of dust emitting the infrared radiation are given. Most sources have temperatures of 200–350 K, which is a consequence of observational selection. No relationship between optical depth of the 10‐μm band and temperatures was found.
