Some of the various magnitude scales for the comparison stars are collected 
in Table 42. It will be seen that the Hagen scale is very much compressed, 
the interval between F and c being only 2.6 magnitudes, whereas it is 4.81 by my 
measures and 4.85 by the Harvard measures. This may be due in part to the 
yellow color of the star F, but seems mainly due to the star c. No magnitudes 
have heretofore been published for stars suitable for comparison with the variable 
near minimum, evidently because it has not been observed at that part of the 
light curve. 
The redness of the variable is given as 4.0 in Chandler’s Third Catalogue. 
Photographically it is at least one magnitude fainter than r at minimum.
