  I developed a new pure-python pipeline to reduce photometric and polarimetric
data: ASTROPOP. It has been designed and optimized to work fully automated with
the IAGPOL polarimeter of Pico dos Dias observatory (OPD, Brazil) and can
reduce photometry and polarimetry data from other instruments, especially from
SPARC4, a multi-channel polarimeter that has been developed for OPD. We present
the results produced by this new code, and compare them with those obtained
from PCCDPACK, a traditionally used IRAF package developed for IAGPOL. We also
propose to use this code for automatic photometric reduction for the new ROBO40
telescope, also installed at OPD. ASTROPOP is fully open source and distributed
under the BSD-3 clause license.
