... You are referred to Section 17.3 for extensive discussion of the many common keywords in the cg suite of software. cgspec allows you to display an image, and then overlay small plots of spectra at different locations on the image. ... In addition, you can bin the spectra up over some spatial region centred on the given locations. cgspec uses the value spectrum for the keyword type to indicate that spectra are to be extracted from that image listed in the keyword in . ... Unset for no spatial binning...

These lamp spectra are compiled from imagestaken during February and June 1996. The images were taken with the newest lamp configuration (lamps pointed down toward closedmirror covers).
