But the catalogue gave its magnitude, its co-ordinates, and its spectraltype.
2
Morey set to work at once with the telescope; trying to find the nearest star of spectraltype G-0, as had been agreed upon.

1
Make one high open ended roll to determine the star's spectralclass.
2
Throughout human history Tau Ceti was a nondescript fifth magnitude star of spectralclass K0.
3
First, the star's color is determined by the spectralclass, as shown on the chart.
4
A main-sequence star, luminosity one, spectralclass G, right in the middle of the Hertzsprung-Russell diagram.
5
The columns each denote a spectralclass, from temperature rating 0 to 9.
6
Once that is determined, roll one percentile die to determine the star's relative temperature rating within the spectralclass.
7
Once the spectralclass of the primary has been determined, find the stellar type by rolling one percentile die:
8
Find the spectralclass along the top of the chart and then roll to find the natural satellite grouping and number:
9
The spectralclass (color and temperature) and stellar type (sequence) of any star are determined as per the procedure below.
10
The average velocities of the brighter stars of the different spectralclasses, as determined with the D. O.
11
Stomatopod crustaceans have complex visual systems containing up to 16 different spectralclasses of photoreceptors, more than described for any other animal.
12
The first order of business was to isolate and determine the exact spectralclasses of the most brilliant stars in the vicinity.
