Vega article in NK

[Paolo Ulivi]

Hi all,
I have been reading the translation of the article on the Vega exploration of comet Halley (NK 05/2006), but there is a sentence that my translator is having trouble translating correctly.
At one point the author says that a model of what the comet should look like was built using the results of Halley's observations " ?@>H;K5 3>4K"
What does this mean? Does it mean simply the observations carried out during the previous year or does it mean the observations of Halley on the previous return to perihelion?
Any idea?

At one point the author says that a model of what the comet should look like was built using the results of Halley's observations "В прошлые годы"

something like "observations being carried out past years" (literally).

Thank you. It was just a little doubt
