Sagittal section for P4 and P14 mouse brain

Dear Community,

Does anyone know the distance in um between the sagittal sections for the P4 and P14 mouse brain in the interactive reference atlas?

Thank you so much,
Adele

As described on this page, the interval between the annotated sections for the P4 and P14 are 160um and 125um respectively.

Sections for the atlases were taken every 20um or 25 um respectively, but not every section was annotated.
Table 1 in the Reference Atlas white paper on the Developing Mouse Atlas documentation page provides these values.
