Stars and other cosmic objects in "Capsule"

Whenever you observe a star, you are measuring information it radiates through electromagnetic wave. In practice, the spectrum of the star, averaged over long period of time, would be attained. Details aside, a major gameplay element of "Capsule", signal analysis, has been inspired from real-world practices. The player accumulates raw signal from a telescope; The signal then must be decomposed into several spectrums. Available spectrums from cosmic objects are quite limited, so this process could be done by brute force, comparing the raw signal with every possible spectrums. However, the player could exploit their prior knowledge about the object of interest to both reduce the number of trials and increase the accuracy of the final result.
