A. Rules and Regulations for Creating Setup and Source Decks

	The following section describes the cards needed to produce
either a "Setup" or "Source" deck.  If the deck has been specified as
a "CONT" deck on the "O" card, then some of the parameters dealing
with spectral line observations will not be used and must be left
blank.  If the deck is a "LINE" deck, then the continuum parameters
must be left blank.  We recommend that neither "LINE" or "CONT" be
specified on the "O" card and that you supply all the information on
all the cards.  "Setup" and "Source" decks differ in whether or not
the deck contains one or more 'S' cards.  "Setup" decks are used for
interactive programs run from the operator's console while source
decks are used for less interactive programs.

	In the following, integer fields, specified by I's, must be
right justified.  Floating point fields, designated by XXX.XX can be
placed anywhere in their fields; the decimal point MUST be supplied
but it need not fall in the depicted column.  Character fields must be
left justified and are designated by A's.  'H', 'M', 'S', and 'D'
refer to angular coordinates.  The type of card is designated by the
character you place in the first column (i.e., 'O', 'R', 'A', 'L',
'P', 'D', 'C', 'S', and ' ' [unlabelled cards).  Column 2 must be left
blank.  (The unlabelled and descriptive origin cards are described
fully in the CAO, pp. 41-42 and App. A)

	You cannot exceed the column limits for any field on any card.
Each deck must start with an "O" card and end with an end-of-file ($$
in columns 1-2 of a physical card; do not insert a $$ in a floppy or
tape file).
