Scientific paper

In order to measure proper motions for known L and T dwarfs we observed a sample of the known L and T dwarfs from the online dwarf archive (detailed in Tables 1 and 2, see http://spider.ipac.caltech.edu/staff/davy/ARCHIVE/ for discovery references) with J-band magnitudes of less than 16.5. 143 of these objects were presented in Jameson et al. (2008, Cat. J/MNRAS/384/1399). To complete the sample, 125 additional objects have been observed, 91 with declination (Dec.) between -30{deg} and +60{deg}, and 34 with Dec. of less than -30{deg}. This first group were imaged using WFCAM on UKIRT over the period of 2006 June to 2008 March. The second group were imaged using SofI on the NTT between 2007 April 2 and 2007 August 31.
