The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

... Abstract Find a unit quaternion corresponding to a specified rotation matrix. ... If r rotates vectors by an angle of R radians about a unit vector a, where R is in [0, pi], then if h = R/2, q = ( cos(h), sin(h)a , sin(h)a , sin(h)a ). ... The CSPICE routine q2m_c is an one-sided inverse of this routine: given any rotation matrix r, the calls m2q_c ( r, q ); q2m_c ( q, r ); leave r unchanged, except for round-off error. ... Version -CSPICE Version 1.1.0, 21-OCT-1998 (NJB) Made input matrix const. ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...

... We describe a new library (AST) which provides a flexible high-level programming interface for handling world coordinate systems in astronomy and for producing graphical output. ... Relationships between coordinate systems are represented within AST by objects called Mappings. ... While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... Like all objects, a Frame also provides methods. ...
