Next: How to get Up: Introduction Previous: Introduction . ... However, we cannot make all our observations at the same time, or at the same place in the sky. ... To do this, we must distribute the observations so that the main independent variables (such as airmass, star color, and instrumental temperature) are uncorrelated with each other. ... As some (like temperature) are inherently likely to be correlated with time, it is doubly important that others (like airmass) be uncorrelated. ...

Astronomical Data Analysis Software and Systems XIII ASP Conference Series, Vol. ... Skysoft is a YAASD (Yet Another Astronomical Software Directory), but with a different overall approach.

... One of these factors is how the client application uses VDPAU; i.e. the number of surfaces allocated for buffering, order of operations, etc. ... At a bare minimum, the application must allocate one video surface for each reference frame that the stream can use (2 for MPEG or VC-1, a variable stream-dependent number for H.264) plus one surface for the picture currently being decoded. However, if this minimum number of surfaces is used, performance may be poor. ... Performance Levels . ...
