... The available observational data on masses and/or luminosities of binary components and the current models for different chemical compositions of Pop I stars were used to improve the mass-luminosity relation for stars of moderate masses. ... This technique was also applied to decompose the low-mass components of several stars suspected to be unresolved binaries. ... The method is based on the minimum determination technique applied to functions of several variables covering a limited range of values...

See SBIG or APOGEE for instructions on building and installing the software for your camera. It helps to have a recent Linux operating system installed. ... Edit protocol.h for the filter wheel and maximum filter count in your system. With recent versions of Linux, ds9, and xpa you must add this to the local profile (e.g. in /etc/profile.local for global use): export XPA_METHOD=local Otherwise, you will see an error message when ds9 starts, and xmccd and ds9 cannot communicate. ...
