Abstract for MTS:
J, H and K mosaicking of star clusters in the LMC in order to obtain integrated spectra. Central mosaic and offset to individual stars. Each band is an individual OB. Please, position the acquisition FOV as closely as possible like shown in the zoom FC, even if it means that the brightest object is not centred.
But don't kill yourselves over this! With the coarse FCs, a very accurate positioning is not possible and not necessary. Uncertainties of 1-2" are fine!
They provide their own telluric standards for each OB, hence the "special calibrations".
They have not submitted FCs for the telluric standards and know that an OB will not be repeated if confusion about the acquisition of the telluric standard could have been avoided with an FC present. As there is only one sky for each calibrator please offset to a "proper" sky if there's a star in their offset (sky) exposure. Please also make note of stars that appear in the sky frames of the science OBs.
