There are 8 stars with temperatures determined using both TCS data and published narrow band data. For these stars, the mean difference in determined temperatures is 0.33 per cent, with a standard deviation of 1.43 per cent. These differences may be regarded as satisfactory, and we have taken an average of the two sets of temperatures for these overlapping 8 stars, to be included in the total of Class III stars using TCS data. The regression relations between temperature and photometric parameters for all these stars, together with the standard deviations, are included in Table 4 (click here).
Unlike the situation for Class III stars, there are few overlapping
published data for Class V stars, so we use the TCS data alone.
The regression relations between temperatures in the two ranges
6000 K to 9500 K, and 4200 K to 6000 K, and photometric parameters are
included in Table 4 (click here).
Discounting the relation with 
, the most useful
parameter for representation of temperature is 
,
with a standard deviation of 1.04 per cent.
Relations between photometric parameters and temperatures for all ESO stars of Class III and Class V are included in Table 4 (click here).
