... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ...

Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...

. A filament stretches across the lower half of the Sun in this image captured by NASA s Solar Dynamics Observatory on February 10, 2015. Filaments are huge tubes of relatively cool solar material held high up in the corona by magnetic fields. Researchers simulated how the material moves in filament threads to explore how a particular type of motion could contribute to the extremely hot temperatures in the Sun s upper atmosphere, the corona.
