On this Picostat.com statistics page, you will find information about the CYGOB1 data set which pertains to CYG OB1 Star Cluster Data . The CYGOB1 data set is found in the HSAUR R package. Try to load the CYGOB1 data set in R by issuing the following command at the console data("CYGOB1"). This may load the data into a variable called CYGOB1. If R says the CYGOB1 data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") and then attempt to reload the data with library("HSAUR") followed by data("CYGOB1"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing CYGOB1 at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the CYGOB1 R data set. The size of this file is about 800 bytes.
CYG OB1 Star Cluster Data
Energy output and surface termperature for Star Cluster CYG OB1.
A data frame with 47 observations on the following 2 variables.
log survface termperature of the star.
log light intensity of the star.
The Hertzsprung-Russell (H-R) diagram forms the basis of
the theory of stellar evolution. The diagram is essentially a
plot of the energy output of stars plotted against their surface
temperature. Data from the H-R diagram of Star Cluster CYG OB1,
calibrated according to VanismaGreve1972 are given here.
