Command line

atlas [files ...] [-c FILE] [-p NAME] [-m MODE] [--tile-columns N]
      [--enable TOOL] [--disable TOOL] [--list-profiles] [-h]

Run atlas --help for the same list from the program itself.

Arguments

files

Zero or more FITS files, each opened into its own frame. Shell globs work: atlas *.fits.

Options

-c FILE, --config FILE

A YAML configuration file. See Configuration.

-p NAME, --profile NAME

One of the bundled profiles: minimal, viewer, detector.

-m MODE, --mode MODE

Display mode, single or tile, overriding the configuration.

--tile-columns N

Columns to use when tiling. Omit it to let atlas pick a roughly square grid.

--enable TOOL

Turn a tool on. Repeatable. Valid names are header, histogram, shm, statistics, tap_subtraction, zmq.

--disable TOOL

Turn a tool off. Repeatable.

--list-profiles

Print the bundled profile names and exit, without opening a window.

-h, --help

Print usage and exit.

Exit codes

Code	Meaning
0	Normal exit, including --list-profiles
2	The configuration was rejected; the reason is printed to stderr

A rejected configuration is caught before any widget is created, so atlas either starts with the features you asked for or does not start at all. It never opens a window with a feature silently missing.

Examples

atlas                              # defaults: single frame, header panel
atlas image.fits                   # open a file straight away
atlas *.fits --mode tile           # every file in its own tile
atlas --profile minimal            # image display and nothing else
atlas --config observing.yaml      # your own configuration
atlas --profile detector --disable zmq
atlas image.fits --enable histogram --enable statistics

Running from a checkout without installing:

PYTHONPATH=src python -m atlas.main --profile viewer image.fits
