... E1 Apertures Kailash C. Sahu March 9, 2004 ABSTRACT A calibration program was carried out to determine the spectroscopic LSFs at the pseudo-aperture locations (E1 apertures) for the first order CCD modes. Observations were taken with the narrowest 52X0.05 acrsec slit to minimize the effect of the aperture on the determination of the LSFs. ... The dotted lines are the LSFs obtained at the nominal aperture locations and the solid lines are the LSFs obtained at the pseudo aperture locations. ...

Plans are under way to create a new way of performing non-interactive observations which will be called auto-observing . ... Non-interactive observing with CIMA has for a long time been available with the use of CIMA command files. Contrary to normal command file observing which requires a command file with a set of commands to be executed sequentially, auto-observing will use a list of sources and a list of instructions on how to observe each of the sources. ...
