NOISE AT 300 NM: Typically 10'^ - 2x10"-^° W/cm^nm in current mode with 0.5-sec 

 integration time 



CALIBRATION SYSTEM: Internal wavelength and intensity mounted on integrating 

 sphere; external 200-W standard lamp mounted on jig 



COMPUTER SYSTEM: IBM-compatible portable with two 1.4 Mb minifloppy drives; 

 larger unit is being considered 



COMPUTER SOFTWARE: Menu-driven package which allows scheduling any number of 

 scans at different times during the day for unattended operation. Scans may 

 include automatic intensity- or wavelength-calibration runs. Scans may be broken 

 up into any number of segments with different sensitivities, wavelength 

 increments, etc. for each segment. All data is stored in binary form. A 

 separate program will print, graph, or convert to ASCII format the raw data for 

 use in data-base programs.
