In all these tests, stability ade quate to give an angular resolution of two seconds of arc was demonstrated' Æthãugh therã is little doubt about the basic feasibility of the large high-resolutìon array, antl although the performance of the entire system Copyright © National Academy of Sciences.

Based on existing alata, it appears virtuaþ certain that the presently approved, but unfunded, additions will prove highly successful. In tÏis case, a further increase in the available equipment by a factor of about two will 52 ¡ll Copyright © National Academy of Sciences.

Examples from the recent past of such new developments include the iletection of the quasi-stellar sources, radio emission fàm flare stars, and the use of lunar occultations to achieve resolution' Nevertleless, the Panel sees some areas in which signiûcant instruments are clearly justiûed, and presents these here as examples of suitable projects for support. These include large telescopes suitable for millimeter wavelengths; thes" may be steerable paraboloids up to 60 feet in diameter, antl ,rp to $2 million.

Thus tle Panel recommends that approximately $30 million be provided over tlie next ten years for proiects of this nature. The limited power of such instruments shou-ld not be misconstuueil as an indication that ttrey are unimportant' In many cases, they will be capable of producing certain speciffc data beyond the capabilities of the giant instruments to produce; an example is the study of flare stars, to which the valuable time of the maior instuuments cannot be assigned, But more important, these lesser instruments will probably provide the principal practical experience to graduate students, and thus snongly influence the quality of personnel available in tle latte¡ portion of the dec ade.

However, such an installation would cost perhaps $15 millíon, and the Panel considers that the data per dollar tlrat might accrue ftom such an installation a¡e not commensurate with tle data per dollar to be produced by the instruments proposed above. Furthermore, since such installations have had practical utility for space and military operations, they have hitherto found sources of funds through agencies that do not ordinarily contribute to conventional asbonomical instrumentation.
