Polarimetric data for 27 stars in the region of Stock 16 cluster obtained using the Torino five-channel photopolarimeter attached to the 2.15 m telescope at the Complejo Astron'omico El Leoncito in San Juan, Argentina. The stellar identification (column 1) are given by Turner (1985ApJ...292..148T) and we also included 4 stars indicated as A, B, C, D, not observed by Turner.
In table1.dat, for each star in all the filters (UBVRI) are given the polarization percentage average (P_lambda, column 2) and the position angle of the electric vector (theta_lambda, column 3) with their respective mean errors computed according to Maronna, Feinstein and Clocchiatti (1992A&A...260..525M).
The polarimetric observations in the five filters were fitted in each star using Serkowski's law (Serkowski, 1973, in IAU Symp. 52, Interstellar Dust and Related Topics, ed. J. M. Greenberg H. C. van de Hults (Dordrech: Reidel), p. 145) in table2.dat. In columns 2 and 4 are listed the values obtained for Pλmax and lambdamax with their respective errors. The column 3 shows the unit weight error of the fit (sigma1), to quantify the departure of our data from the theoretical curve of Serkowski's law. In the column 5 is listed the dispersion of the position angle normalized by the average of the position angle errors (ɛ).
