Minor modification of graphical output. * Feb. 2004: New search option available: Searches are possible within a predefined group of species, e.g. only those already observed in the ISM or CSM besides searching for all molecules in the database or specified ones. * Sep. 2003: Added additional output option and removed small bugs. * Aug. 2003: Several changes; including default values for all selections except the molecules. Output as text can be sorted by species (followed by frequency), be frequency, or by intensity. Graphic output has been optimized. * July 2003: Removed bug that caused wrong //A// values if frequencies were requested in units of cm<sup>−1</sup> and another one that took the decadic logarithm of lg(//Sμ//<sup>2</sup>). Minor modification of search page. * Mar. 2001: The //A// value (base 10 logarithm) can be requested instead of the intensity at a certain temperature. * Feb. 2001: A recalculation of the intensities of a search output can be requested for 300 (default), 225, 150, 75, 37.5, 18.75, and 9.375 K.
