... We intend to use the restored HST to study age structure and chemical evolution of the stellar population at the center of the LMC. ... To study the reduction techniques needed, a set of simulated PC images have been made. ... Two of the generally available photometric software packages, ROMAFOT and DAOPHOT, have been used to analyse the images. Results show that the photometric accuracy reached with these packages is not enough for high precision photometry in this configuration. ...
