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 star‐
convert 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 argu‐
ments 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.
