We present Doppler Images of the RS CVn binary system HR 1099 ( V711 Tau ) from spectra taken in two different sites , KPNO and MSO , during the MUSICOS 1998 campaign .
Contemporaneous APT photometry is used to constrain the Doppler Images .
The resulting maximum entropy reconstructions based on the least-squares deconvolved profiles , derived from \sim 2000 photospheric absorption lines , reveal the presence of starspots at medium-high latitudes .
We have obtained maps for both components of the binary system for the first time .
The predominant structure in the primary component is an off-centered polar spot , confirming previous works on the same target by using independent codes .
The result is verified by using both data sets independently .
The lower spectral resolution data set gives a less detailed map for the MSO data set .
The images obtained for the secondary component show a low latitude spot around orbital phase 0.7 .
This spot seems to mirror the structure seen on the primary .
It might suggest that tidal forces may influence the spot distribution on this binary system .
