The Run is J-band imaging of the inner 10" of the jet of 3C273, and consists od 15 OBs which differ only in the fact that there are slight (intentional) shifts of the whole offset pattern from one OB to the other. Please center the target on pixel (450,390) during acquisition. *** IMPORTANT: During a science template, the hour angle MUST be INSIDE the range [-1h 05m, 1h 05m]. Otherwise, the QSO's diffraction spike will cross the jet and the corresponding images will be wasted. The QSO's right ascension is 12h 29m 06.7s. This means that the science templates should be started AFTER LST 11:25, but BEFORE LST 12:50.
