Zevachim 6:1-2

Zevachim 6:1

Rabbi Yosi says that if kodshei kodashim (most-holy sacrifices) were slaughtered on top of the altar, they are considered to have been slaughtered in the north. Rabbi Yosi bar Yehuda says that from the middle of the altar to the north counts as the north and from the middle of the altar to the south counts as the south. The handfuls of the flour offerings could be taken anywhere in the Temple courtyard; these were eaten within the courtyard hangings by male kohanim, prepared in any manner, for one day and one night, until midnight.

Zevachim 6:2

A sin offering of a bird was prepared at the southwest corner of the altar. Melikah (nipping the head) was valid anywhere but this was the place to sprinkle the blood. The southwest corner served three purposes below the red line and three above: sprinkling the blood of a bird sin offering, bringing near a flour offering and pouring out the remaining blood of sacrifices were performed below; water libations and wine libations were performed above, as were bird burnt offerings when they were too numerous to be done in the east.
