Like.
In that case, one would need additional spectral detail, such as measuring with two or more bands. -
GGleb1964 replied to the thread I Why use Stefan's Law to measure temperature?.It's quite simple: if the source's angular size is below the resolution limit, it becomes diluted into the point spread function. If the...
