Differentiation of vectors
... The grad of every smooth scalar field is a vector field. It is natural to ask whether all vector fields are the grad of some scalar field. In general, the answer is “no”, but we can characterise those vector fields F for which this is the case. If there exists a scalar field φ such that the vector f ...

pix_get_grating_wavelength Synopsis Syntax Description
... Calculates the wavelength, in Angstrom, for a given grating position and using the current pixlib settings. The x and y values are in the GAC coordinate system, and so represent the grating dispersion and cross−dispersion angles in degrees. The grating order − as set by pix_set_grating() − must be n ...
