**Figure** -- Lines with zero redshift

This application creates a chart stacking the MOSAIC spectrograph wavelength coverages and
an ESO Earth atmospheric model. This may serve either as a reference to MOSAIC wavelength invervals for each
mode (on this, see also ``list-mosaic-modes.py``) or to verify the Earth atmospheric emission/trasmission
in a wavelength region of observational interest.

It is also possible to inform a redshift so that the chemical lines will be accordingly displaced:
