The Nearby Field Galaxy Survey

093 A11392+1615 Alsp known as AKN 311 and Holmberg 275. May form a pair with a galaxy 2.3´ to the west.
094 NGC 3846 Highly asymmetric light distribution. Outer parts look tidally disturbed.
097 NGC 3913 Also known as IC 740. The faint spiral structure appears to wind both clockwise and counterclockwise.
105 A12001+6439 Also known as Mrk 195.
116 NGC 4288 Also known as DDO 119.
119 A12195+7535 Seyfert I galaxy Mrk 205, classified as compact elliptical, seen through the spiral disk of foreground galaxy NGC 4319.
120 A12263+4331 Also known as D 129.
130 NGC 4841B Fainter of the two galaxies, to the northeast of brighter galaxy NGC 4841A. These two galaxies have a large overlap on the sky, resulting in shallow photometry.
151 NGC 5491 An apparent smaller companion is located 25´´ north of the nucleus.
152 NGC 5532 A smaller companion galaxy, 0.5´ south of the center of this elliptical, is overlapping the outer parts.
153 NGC 5541 Also known as AKN 444.
154 NGC 5596 Also known as Mrk 470.
158 NGC 5762 Harbors a very extended and low surface brightness flocculent disk.
159 A14489+3547 Shows a highly warped, banana-shaped disk and forms a pair with A14492+3545.  Also known as II Zw 70 and VV 324.
160 A14492+3545 Forms a pair with A14489-

 

+3547 (see remark above) and shows the morphological signature of a polar ring. Also known as II Zw 71 and VV 324.
161 IC 1066 A large barred spiral galaxy is located 2.1´ North of this galaxy.
163 A15016+1037 Seyfert I nucleus. Aka. Mrk 841.
166 NGC 5875A Named A1507+5229 in CfA I.
169 NGC 5940 Galaxy with a weak Seyfert I nucleus; also known as Mrk 9030.
171 NGC 5993 Two stars are superposed on this galaxy on either side of the nucleus. This galaxy as well as its neighbor 2.4´ to the southwest (not in this sample) show hints of tidal features and are probably in interaction.
173 IC 1144 Also known as Mrk 491.
175 A15523+1645 Also known as AKN 489.
181 NGC 7077 Also known as AKN 549.
183 A22306+0750 Also known as II Zw181 and AKN 558.
193 NGC 7620 Also known as Mrk 321.
194 A23264+1703 Harbors a double nucleus and shows tidal features of an ongoing interaction with a smaller companion.
196 NGC 7752 Strongly interacting companion of NGC 7753 with one of the tidally disrupted arms of NGC 7753 causing a starburst on one side of NGC 7752. Also known as AKN 585, IV Zw165 and VV 5.
197 A23514+2813 Named NGC 7777 in CfA I.
-- (NGC 4319) Foreground spiral galaxy through which A12195+7535 is seen.

2.B  Calibration of the Intensity Profiles

We photometrically calibrated the radial intensity profiles by solving simultaneously for the calibration equations for B and R, or U and R, using (B-R) and (U-R) color terms, respectively. Consider the pair of calibration equations for the B and R intensity profiles:

  µB(r)   =   µB,i(r) + pz1 - pe1 · X1 - pc1 · (µB-µR)(r)
µR(r)   =   µR,i(r) + pz2 - pe2 · X2 - pc2 · (µB-µR)(r)
, (2.1)

where µ\lambda,i denotes the surface brightnesses in B and R in instrumental mag, pzn denote the photometric zero points, pen the specific atmospheric extinction coefficients and Xn the air mass at the middle of the exposures, and pcn denote the color term coefficients corresponding to our choice of reference filters.  
If we denote by Pn(r) the terms that are independent of color, µ\lambda,i(r) + Pzn - pen · Xn , we can rewrite equations (2.1) as

  (1+pc1) · µB(r)   =   P1(r) + pc1 · µR(r)
(1-pc2) · µR(r)   =   P2(r) - pc2 · µB(r)
, (2.2)
