Each sequence of calls to one of the image I/O routines is associated with a unique identifier, the so called transfer identifier. Before the first call, 0 should be assigned to this identifier. When upon return the identifier has a value < 0, an error has occurred. ... These further calls must be made using the unmodified transfer identifier. ... With the help of this identifier, it is possible to handle subsets which contain more data than there is room for in your read/write buffer. ...

. This diagram shows how the precedence rules may be used to achieve the effect of hidden internal borders. The two by two table is surrounded by a solid border. The HTML table specification and style rules following the image cause the vertical border between the two cells in the first row and the horizontal border between the two cells in the first column to disappear.

... spectrum . ... The photons we detect originate in the outermost layers, or atmosphere, of the star. In order to interpret stellar spectra, it is necessary to construct models which accurately represent the structure of a stellar atmosphere and the transfer of radiation from the stellar interior into interstellar space. For the study of helium stars and other stellar remnants, we in Armagh use several computer programs, of which sterne and spectrum are the most important. sterne . ...
