... We give evidence that lower pressure model chromospheres can alos reproduce the Balmer line profiles, but give Lyman surface fluxes overestimated by more than an order of magnitude. ... We obtain the Paschen lines in emission and Paschen decrements as large as 41 for Pa$_{\beta}$. ... Formation of all Hydrogen series is collisionally controlled and takes place in a rather thin layer at the top of the chromosphere (Balmer, Paschen, and Brackett) or in the transition region (Lyman). ...

The first character in each record (line) of formatted output defines a carriage control character to the lineprinter, often called ASA-character, for a previous name of the US Standardization Organization ANSI. ... When using VAX/VMS for output first on a file, which is to be printed later on paper, it is advisable to use the extension .DAT . ... You use the compiler switch -vms f77 -vms prog.f and get the control characters removed from the screen output. ...
