Inspect a dataset

This mode works in the same way as the Line Analysis module in CASSIS. For a given species, the program searches for transitions within the observed range(s). Only transitions within the spectroscopic constraints provided by the user are selected. The transitions are displayed over the bandwidth provided by the user.

Overview of the configuration keys

Mandatory	data_file	path to the datafile
	inspect	list of tags
	bandwidth	width in km/s of the window around each transition
Optional	franges_ghz	list of frequency ranges to inspect
	thresholds	thresholds on the spectroscopic parameters

Mandatory keys

• data_file

• inspect

• bandwidth

Optional keys

• franges_ghz

• thresholds

• plot_gui

• plot_pdf

• v_range

• options for the display (to come)

Workflow

• The program reads the file given with data_file

• If franges_ghz is provided, data are selected over these frequency ranges

• For the list of tags provided by inspect, the program searches the list of transitions (eventually matching the constraints provided by thresholds)

• It creates a list of windows centered on the line’s frequency and of width bandwidth

• If plot_gui is true, the windows are displayed on the screen.

• If plot_pdf is true, the windows are displayed in a multi-page pdf (new page for each species).

• If v_range is provided, the specified velocity ranges are displayed as green regions.
