- Model channel maps from molecular line emission of discs by fitting intensity and rotation velocity
- Study the disc vertical structure by modelling front and back side emission surfaces
- Compute moment maps that accurately capture complex line profile morphologies
- Extract rotation curves, radial and meridional velocities, intensity and line width profiles
- Analyse the disc dynamical structure by modelling Keplerian motion + pressure support + self-gravity at once
- Identify velocity and intensity substructures; study their coherence and degree of localisation
- Non-axisymmetric models are possible; all attributes can be described as a function of
$R,\phi,z$ disc coords
Discminer offers a wide range of analysis and visualisation tools to fully explore the physical and dynamical structure of your disc.
- Compute moment maps that accurately capture complex line profile morphologies.
- Output moment maps include peak intensity, line width, line slope, and centroid velocity.
- Easily clip, downsample, and convert to brightness temperature units.
- Quickly visualise model versus data channels and interactively extract spectra.
- Extract azimuthal and radial profiles of intensity, line width and velocity from moment maps.
- Compute rotation curves and decompose disc velocity into its three-dimensional components.
- Reveal large-scale signatures and quantify their pitch angle, width, extent, and coherence degree.
- Identify small-scale velocity and intensity perturbations, and estimate their localisation degree.
- Customise intensity channels and residual maps, and highlight coherent and localised perturbations.
- Use sky or disc projections interchangeably for easier visualisation of features.
- Easily overlay the disc geometry (orientation and vertical structure) on any observable product.
- Overlay 1D profiles or 2D maps from external data to e.g. highlight the presence of dust substructures.
