Catalogues were searched to see if proper motions of the photometric standards were already known. The Lowell Observatory Bulletins were used for proper motions of the Giclas named stars, and the Radcliffe Catalogue of Proper Motions for the Selected Area stars. These proper motions have been adopted here, except where noted. If no object of the same name exists in the user's own catalogue the telescope will automatically set at a position based on the data presented here. On the INT and JKT no more than 500 sources can be held in memory, so the catalogue has been split, at Reynier Peletier's suggestion, into four parts.
Users can then read in any three parts and have sufficient coverage for the night.
136 Other catalogues available to the INT and JKT are listed in Technical Note 85. The table lists positions of the standard stars and the photoelectric photometric data measured by Landolt on the 1.5m telescope at the Cerro Tololo Observatory. Magnitudes as well as colours are given to help the observer determine a suitable exposure. Giclas, H.L., 1963. No. 120 and following.
