@adgjmp: Your adapted script seems to target requirements not covered by your first spec. Be aware that it's best to prepare a decent, detailed spec covering the entire problem in order to avoid waste of resources and efforts.

starconvert
starconvert(1) General Commands Manual starconvert(1)
NAME
starconvert - convert text data files to StarPlot format
SYNOPSIS
starconvert [ options ] spec-file input-file [ output-file ]
DESCRIPTION
Although many stellar data files are publicly available on the Internet from NASA and other astronomical organizations, there is no set
format for these files. The program starconvert acts as a buffer between this confusion and the format in which StarPlot requires data
files. To do so, it uses a specification file that details how various fields of stellar data (name, distance, right ascension, etc.) may
be extracted from the original data file.
On the StarPlot web site are available some packages of data that include both an original data file from NASA, and also a specification
file. These packages are referred to as "data sets", from which starconvert can produce a data file in StarPlot format. For ease of use,
this should be done via the starpkg(1) shell script.
The starconvert command uses the specifications in spec-file to convert input-file to StarPlot data format and writes the results to out-
put-file if specified, or standard output if not. The first two arguments are required. Exactly ONE may be replaced with a dash `-' for
reading from standard input.
OPTIONS
-- Signals the end of the options. This allows you to use a spec-file whose filename begins with the '-' character.
--add-sun
Add an entry for the Sun to the generated StarPlot-format data file, if it is not already present in the original raw data file.
This is the default behavior, so this flag has an effect only if it reverses an earlier --no-add-sun flag.
--no-add-sun
Do not add an entry for the Sun to the generated StarPlot-format data file, unless it is present in the original raw data file.
Adding the Sun is otherwise done by default, since most star catalogs do not include it.
SPECIFICATION FILES
For detailed information on how to write a specification file, see the example file listed below. Be aware that I expect to change the
default format of starconvert spec files after version 1.0, although starconvert will remain backwards-compatible.
FILES
/usr/share/doc/starplot/ - Contains documentation
/usr/share/doc/starplot/examples/example.spec - Example specification file
