Method of eye estimates of stars without steps.
1) Find the variable star and the comparison stars marked in
the map.
2) Seeing the the variable star, try to imagine its location
in the brightness interval between the reference stars.
3) Looking at the specially prepared scale, try to reproduce
the location of variable in the brightness scale from memory.
The scale may be arbitrary and visual, if the reference
stars have not been measured. The grades of arbitrary scale
are marked relative to brightness intervals between the
reference stars.
