Spectral indices of radio loops [PDF]
Journal of Physics: Conference Series, 2010 Observations of the continuum radio emission at 1420, 820 and 408 MHz enabled estimations of the brightness of the radio loops. We calculated the mean brightness temperatures and surface brightnesses of the six main Galactic radio-continuum loops I-VI at the three frequencies. We have demonstrated the reality of Loops V and VI and presented diagrams of

Combining spectral and textural information in UAV hyperspectral images to estimate rice grain yield
International Journal of Applied Earth Observations and Geoinformation, 2021 The speedy development of UAV (Unmanned Aerial Vehicle) has provided more data choices for crop yield estimation. In most cases, spectral information derived from multispectral or hyperspectral images is used alone for yield estimation, while variables ...

IR-Radio Spectral Indices for Be Stars [PDF]
Symposium - International Astronomical Union, 1994 Using published data and new data from mm observations, we calculate spectral indices α(12μ-25μ), α(25μ-1.1mm) and α(1.1mm-2cm) for Be stars. The index α(25μ-1.1mm), obtained for 8 stars, shows two characteristics: 1) for “normal” Be stars the index decreases from earlier types towards later types, i.e., later type Be stars tend to have shallower ...
