Star formation timescale in the molecular filament WB 673

<p>Ammonia lines data in molecular filament WB 673. Files WB673_NH3_11.fits, WB673_NH3_22.fits and&nbsp;WB673_NH3_33.fits&nbsp;correspond to maps in lines NH₃ (1,1),&nbsp;NH₃ (2,2) and&nbsp;NH₃ (3,3),&nbsp;respectively.&nbsp;&nbsp;Data obtained at the 100-m&nbsp;Effelsberg telescope (Germany) and&nbsp;covered the entire area of the filament with a size 10&#39; <span class="math-tex">\(\times\)</span>&nbsp;50&#39;&nbsp;with respect to the minor and major axes.&nbsp;</p>
