place constraints on sth

The planet was discovered by TESS, NASA’s planet-hunting space telescope designed to find exoplanets that pass between us and their home star, by detecting the telltale dimming as the planet blocks a small percentage of the star’s light. The depth of dimming, and the tiny movements of the star as it is very slightly pulled by the planet’s gravity (detected with other telescopes), allow scientists to place constraints on the size and mass of the planet.

According to the context, I can infer that "place constraints on" here means something like "measure" or "calculate". However, I can’t find any related meanings in dictionaries for the word "constraint" or the phrase "place constraints on sth." So my question is that do I just get the meaning through the context, or the meaning of "measure" has something to do with that of "place constraints on"?

Thank you!
