Title: A new PSF-fitting photometry and reddening map for the VVV bulge area

Abstract:
The VISTA Variables in the Vía Láctea (VVV) is a public ESO survey covering about 300 deg² of the 
Galactic bulge, and 250 deg² of the southern disk, with the VISTA telescope in near infrared (NIR). 
We have derived a new point spread function (PSF) fitting photometry for the bulge area of the VVV 
in JK passbands, with unprecedented depth (down to Ks ~ 19.5 mag) and accuracy (σ < 0.1 mag at 
Ks = 17.5 mag), including completeness and systematic error estimations based on artificial star 
injection experiments. This photometric dataset has been used to study the age of the bulge using 
color magnitude diagrams (CMDs) and to derive a reddening map of the whole VVV bulge area, with 
higher resolution and performance than ever before. Both the photometric dataset and the 
reddening map will be made public.
