Abstract

ASTROM performs “plate reductions”. You supply star positions from a catalogue and the $\left[x,y\phantom{\rule{0.3em}{0ex}}\right]$ ccoordinates of the corresponding star images. ASTROM uses this information to establish the relationship between $\left[x,y\phantom{\rule{0.3em}{0ex}}\right]$ and $\left[\alpha ,\delta \phantom{\rule{0.3em}{0ex}}\right]$ enabling the coordinates of “unknown stars” to be determined.
