1. The collimator value is now automatically set to the nominal value of 1000 upon homing systems during instrument startup.
2. Flexure Compensation is now automatically activated upon homing all systems during instrument startup. Additionally, ON and OFF buttons have been added to the Flexure Compensation grey box in the GUI, that allow to turn on or off the spectrograph flexure compensation. Therefore, the green LED, which before had the double function of being a on/off button, is now only an indicator light of the status of the flexure compensation system.

The Goodman High Throughput Spectrograph (GTHS) was built in the Goodman Laboratory at the University of North Carolina under the leadership of Prof. J. Christopher Clemens. It is an imaging spectrograph, capable of producing excellent image quality across a 7.2 arcmin diameter FOV (with a 0.15 arcsec/pixel scale), and spectra at various resolutions from the atmospheric UV cutoff all the way out to 850nm. It employs all transmissive optics, and Volume Phase Holographic (VPH) Gratings to achieve the highest possible throughput for low resolution spectroscopy over the 320-850 nm wavelength range. The paper describing the instrument is Clemens et al. (2004) |
