... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...

... The program will propose reasonable default choices, and will provide some approximate estimates of the magnitudes where photon noise becomes excessive, and where photon and scintillation noise are comparable. ... Table shows what a typical crossover table looks like. ... We would generally prefer to have the extinction measurements limited only by scintillation noise, so the initial faint limit for extinction stars is set 1.5 magnitudes brighter than the brightest of the crossover values. ...

... The firmware (built-in software) in the NexStar 8 GPS and 11 GPS scopes is designed to be updated by downloading a file from Celestron and uploading it from your PC to your scope.  ... To upload the firmware, you need a cable to connect from the serial port on your computer to the PC port on the base of the scope.  The PC port on the base of the scope is a standard RJ-45, so it is fairly easy to build a cable using a flat RJ-45 cable and a DB-9 (female) to RJ-45 adapter.  ...
