“…All of the above values are very similar to those found by Vitores et al (1996b) and place the UCM sample of galaxies in the zone of the late-type spirals, with small bulges and not very extended disks (Freeman 1970). Three remarks are interesting when comparing both sets of data.…”

“…Therefore, despite there is a great variety in morphological and spectroscopic types, a uniformity in the mean surface brightness is exhibited, as was also proved with the red data (Vitores et al 1996b found a slope value of −0.21±0.01). The fit gives a mean surface brightness value of −13.3 mag kpc −2 .…”

Abstract. We present Johnson B surface photometry for the UCM Survey galaxies. One-dimensional bulge-disk decomposition is attempted, discussing on fitting functions and computational procedures. The results from this decomposition, jointly with concentration indices and an asymmetry coefficient, are employed to study the morphological properties of these galaxies. We also compare our results with the previous morphological classification established using Gunn r imaging data and with other samples of galaxies. No major statistical differences in morphology are found between red and blue data, although some characteristics such as size and luminosity concentration vary. We find a correlation between luminosity and size. Several parameters are used to segregate the objects according to their morphological type.

Abstract. Detailed B and R surface photometry is performed for 139 faint emission-line galaxies (ELGs) and for 2 non-ELGs. They are a subsample of the ELG sample selected by Popescu et al. (1996Popescu et al. ( , 1998 towards four nearby voids. We derived the isophotal and integral photometric parameters and radial surface brightness (SB) profiles. Our sample consists mostly of low luminosity (< M B > med = −17.7), small linear size (< d 25 > med = 6.0 kpc) (H 0 = 75 km s −1 Mpc −1 ) and blue (< B−R > med = 0.93) galaxies. About 83% of the studied ELGs belong to the class of Blue Compact Galaxies (BCGs); others are luminous Starburst Nucleus Galaxies (SBNs) and a few interacting pairs. 72% of the ELGs possess a single dominant H ii region, while the remaining 28% show multiple knots. Furthermore 71% of the ELGs show regular outer isophotes, and the remaining 29% reveal disturbed outer morphologies.We performed the SB profile decomposition by means of disentangling the underlying stellar disk and the excess light above the exponential disk. We classified the profiles into 5 types: pure disk profiles (21% of studied 139 ELGs); profiles that show both disk and bulge/nucleus/H ii knot components (37%); profiles that have central light depression (13%); non-disky (concave) profiles (7%); and almost unresolved (quasi-stellar) images and stellar SB profiles (22%). Popescu et al. (1997) found that most of the studied ELGs follow the spatial distribution of "normal" galaxies from the CfA Redshift Survey. 15 ELGs and 1 non-ELG were classified as being well isolated and are distributed within nearby (z ≤ 0.033) voids. We found that these isolated ELGs are almost all dwarf galaxies with Send offprint requests to: J. Vennik Based on observations obtained at the Calar Alto observatory, Almeria, Spain.−18.4 < M B < −12.7, they show similar luminosities and colours as the nearby non-isolated ELGs. For 8 of 15 isolated ELGs an underlying LSBG has been detected. The underlying disks of isolated ELGs tend to be larger and of lower SB, than the disks of non-isolated ELGs (of the same total blue flux).
