The determination of structural parameters of 11 faint Galactic globularclusters that, in most cases, had not been previously studied in this context.The clusters are IC1257, Lynga7, Terzan4, Terzan10, BH176, ESO452-SC11,ESO280-SC08, 2MASS-GC01, 2MASS-GC02, GLIMPSE-C01 and AL3, which are projectednot far from the central region of the Galaxy. Field-star contamination issignificant in the colour-magnitude diagrams. Stellar radial number-density andsurface-brightness profiles are built with 2MASS photometry that, for thepresent clusters, corresponds basically to giant-branch stars. Field-stardecontamination is essential for clusters in dense fields. With decontaminatedphotometry we also compute the total MV of four such globular clusters, usingM4 as a template. King-like functions are fitted to the radial profiles, fromwhich the core, half-light, half-star count and tidal radii are derived,together with the concentration parameter. Parameters derived here are comparedto the equivalent ones of other Galactic globular clusters available in theliterature. Structural parameters and luminosity of most of the faint globularclusters dealt with in this paper are consistent with those of Palomar-like(low-mass and loose structure) globular clusters. This work helps to improvecoverage of the globular cluster parameter space.
