4. Coronal Bright Points: Another Oscillating Environment
... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...

7. Procedures for Observations
... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

19. WISP Observations of the Pleiades in the Ultraviolet
... These partially reduced images of the Pleiades were taken by WISP using its longer-wavelength (2180 ) UV filter. Point-spread functions (PSFs) of the brightest stars have been removed to reveal much of the inner reflection nebula, both in a centralized diffuse glow and in the nebulosity south of Merope, the bottom star in the Pleiades ``bowl''. The PSF removal process was improved since these images were produced. Better ultraviolet images can be found here . ...
