varstar

Type the file name of the .lst file created using the txdump command during reduction. DO NOT type the .lst extension, otherwise an error will result.

Answer the questions asked by varstar. Be sure to use the numbers. The idea is to reduce the error column as much as possible - good values are in the range of 0.004-0.006. To reduce the error column remove the stars with the highest error. This will remove those stars from the final solution. When you are done removing stars type

star

This will create .dat files. You my use the same name used for the .lst file because the extensions are not the same.
