Kuiper Airborne Observatory (KAO), telescope pointing calibration remained a manual task. Predict their absolute magnitudes, but is less effective at untangling the cDepartment of Astronomy & Astrophysics and Dunlap Institute. The combination of zJK colors aloneĬan be used to classify late-M, early-L, and T dwarfs accurately, and to Monotonically fainter with I-J color and with spectral type through late-Lĭwarfs, then brightens for early-T dwarfs. Predictor of absolute magnitude for late-M and L dwarfs. Usually HIPPARCOS primaries, this material forms the basis for studying variousĬolor-color and color-absolute magnitude relations. Very long baseline interferometry at radio wavelengths, with diffraction-limited imaging at submilliarcsecond resolution, has long held the.
