... so as to be bright enough to be heliometrically well determined, and at the
same time not so bright as to blur the photographic images. III. The stars must be
symmetrically situated in position angle about 24 p. This will free the resulting
scale ...

The magnitudes must be between 7.0 and 8.2, so as to lie bright enough to be
heliometrically well determined, and at the same time not so bright as to blur the
photographic images. III. The stars must be symmetrically situated in position
angle ...
Thus the two opposite limbs of the sun, except in the very best observing weather
, do not maintain a steady contact together when heliometrically observed, but
vibrate, alternatelydapping over and receding from each other. In the
observations ...

the same result as that arrived at from the 74 measures in the table above, viz.,

The personal equations depending on magnitude can be best and most easily
studied by observing relative right ascensions of stars in loose clusters which
have been micrometrically measured either heliometrically or from their
photographs.
