THE CATALOG SECTION
The catalog section is used to assign names to columns in the
standard star catalog, and optionally, to associate error columns
with the named columns.
The catalog section begins with the keyword catalog, followed by
any number of name and error(name), column associations.
Syntax
catalog
name number
error(name) number
The first declaration creates a name column number association. It
consists of a name followed by a column number. The name becomes
the variable name for that column.
The second declaration creates an error (name) column number
association. It begins with the keyword error, followed by a name
in brackets and a column number. The name must be the name of an
input column previously declared in the catalog section. The error
declarations are optional.
The column number must be a decimal integer greater than two, since
catalog files always reserve the first column for a matching name.
This name is used to match objects in the catalog file with objects
in the observations file.
Example

V 2
error(V) 3
BV 4
error(BV) 5
