Mosaic Map

The Mosaic Map view presents a summary table of every slit × diffraction-order combination and lets you inspect each one individually.

Overview

Switch to this view by clicking Mosaic Map in the view ribbon. The right-hand sidebar is replaced by a dedicated control panel; the central plot shows the selected slit–order pair.

---

Controls

Compute

Click Compute to calculate all valid slit × order combinations for the current instrument configuration. This must be run at least once before the table appears.

Re-run Compute after changing any instrument parameter to refresh the table.

Metric

Choose what quantity to color-code the table:

Metric	Unit
Wavelength	Å
Resolution	dimensionless (λ/Δλ)

Colormap

Select the Plotly colormap used to render the per-combination plot in the central panel.

Slit–order table

Each row in the table corresponds to one slit in one diffraction order.

Column	Description
Slit	Name of the slit
Order	Diffraction order integer
λ min	Minimum wavelength on the detector (Å)
λ max	Maximum wavelength on the detector (Å)
λ mean	Mean wavelength (Å)
Resolution	Mean spectral resolving power
Valid pixels	Number of lit detector pixels

Click any row to select it. The selected row is highlighted and its 2-D spectral map is rendered in the central plot.
