  Considering features of stellar spectral radiation and survey explorers, we
established a computational model for stellar effective temperatures, detected
angular parameters, and gray rates. Using known stellar flux data in some band,
we estimated stellar effective temperatures and detected angular parameters
using stochastic particle swarm optimization (SPSO). We first verified the
reliability of SPSO, and then determined reasonable parameters that produced
highly accurate estimates under certain gray deviation levels. Finally, we
calculated 177,860 stellar effective temperatures and detected angular
parameters using the Midcourse Space Experiment (MSX) catalog data. These
derived stellar effective temperatures were accurate when we compared them to
known values from literatures. This research made full use of catalog data and
presented an original technique for studying stellar characteristics. It
proposed a novel method for calculating stellar effective temperatures and
detected angular parameters, and provided theoretical and practical data
support for finding radiation flow information for any band.
