Context : Recent studies show that rotation significantly affects the s-process in massive stars .

Aims : We provide tables of yields for non-rotating and rotating massive stars between 10 and 150 M _ { \odot } at Z = 10 ^ { -3 } ( [ Fe/H ] = -1.8 ) .
Tables for different mass cuts are provided .
The complete s-process is followed during the whole evolution with a network of 737 isotopes , from Hydrogen to Polonium .

Methods : A grid of stellar models with initial masses of 10 , 15 , 20 , 25 , 40 , 60 , 85 , 120 and 150 M _ { \odot } and with an initial rotation rate of both 0 or 40 % of the critical velocity was computed .
Three extra models were computed in order to investigate the effect of faster rotation ( 70 % of the critical velocity ) and of a lower ^ { 17 } O ( \alpha, \gamma ) reaction rate .

Results : At the considered metallicity , rotation has a strong impact on the production of s-elements for initial masses between 20 and 60 M _ { \odot } .
In this range , the first s-process peak is boosted by 2 - 3 dex if rotation is included .
Above 60 M _ { \odot } , s-element yields of rotating and non-rotating models are similar .
Increasing the initial rotation from 40 % to 70 % of the critical velocity enhances the production of 40 \lesssim Z \lesssim 60 elements by \sim 0.5 - 1 dex .
Adopting a reasonably lower ^ { 17 } O ( \alpha, \gamma ) rate in the fast rotating model ( 70 % of the critical velocity ) boosts again the yields of s-elements with 55 \lesssim Z \lesssim 82 by about 1 dex .
In particular , a modest amount of Pb is produced .
Together with s-elements , some light elements ( particularly fluorine ) are strongly overproduced in rotating models .
