A model is given for constructing artificial integrated spectral lines which allows the inclusion of all effects relevant to the synthesis of these lines by numerical methods. Among the effects included are noise, limb darkening, the centre-to-limb variation of the shapes and wavelength positions of the spectral line profiles, different laws of the

PARTIENDO DE LOS ULTIMOS RESULTADOS EXPERIMENTALES SUMINISTRADOS POR LAS SONDAS ESPACIALES HELIOS A Y B ASI COMO DEL CONJUNTO DE MEDIDAS DE LA LUZ ZODIACAL OBTENIDAS DESDE OBSERVATORIOS TERRESTRES SE ESTABLECE POR PRIMERA VEZ UN ESQUEMA TEORICO DE LA DINAMICA DE LA MATERIA INTERPLANETARIA. DENTRO DE ESTE ESQUEMA SE ANALIZAN LAS DISTINTAS FUERZAS

From a measurement of the J = 3 - 2 rotational emission line of hydrogen isocyanide, and a literature value for that J = 1 - 0 line (Snell, 1979), the excitation parameters for HNC in the direction of the molecular peak as determined by CO were derived. Kinetic temperatures for the optically thick CO and (C-13)O transitions are about 50 K, while
