2-2   There are several clusters near or within the search radius. Adopted 1161
2-2    (V=21.52, V-I=0.83, R=0.48") since it was closer to the radio position
2-2    than the brighter cluster 1143 (V=21.14, V-I=0.76, R=0.69"). 
2-4   There are several very bright clusters nearby. Adopted 1298 since it was
2-4    the brightest (V=19.07, V-I=0.67, R=0.32"). 
2-4
4-2   On the edge of region C (see Whitmore et al., 1999AJ....118.1551W). 
4-2    Adopted the brightest object (2002, V=19.06, V-I=0.14), which is 0.66"
4-2    from the radio position. The closest object was 2033 (V=20.96, V-I=0.33, 
4-2    R=0.19"). 
4-5   On the edge of region D. Adopted the brightest object (2410, V=18.70,
4-5    V-I=0.13), which is 0.49" from the radio position. The closest object was
4-5    2399 (V=21.69, V-I=-0.04, R=0.30"). 
4A-9  There are several bright clusters just outside the circle, including 3772 
4A-9   (V=20.58, V-I=1.39, R=0.81"). 
4A-16 There are three bright clusters in the circle. Adopted the brightest 
4A-16  object (5105, V=20.58, V-I=0.52), which is 0.29" from the radio position.
4B-2  Adopted the brightest cluster (3069, V=20.92, V-I=0.21), which is 0.46"
4B-2   from the radio position. The closest object was 3003 (V=23.2, V-I=0.81,
4B-2   R=0.45"). 
5-5   There are two good candidates in the circle. Adopted the redder object,
5-5    which is slightly closer to the radio position (7894, V=20.74, V-I=0.99, 
5-5    R=0.26"), but the radio source is probably a combination with 7811 
5-5    (V=19.38, V-I=0.30, R=0.42"). 
7-2   Centered on part of the dust lane near the nucleus of NGC 4038. Adopted 
7-2    the very bright cluster 9089 (V=18.51, V-I=0.07), which is just outside 
7-2    the search radius (R=0.71"), but the true source may be embedded. The 
7-2    closest object was 9182 (V=22.10, V-I=0.88, R=0.31").
9-4   There are several candidates in the circle. Chose the brightest cluster
9-4    (5047, V=21.59, V-I=0.26, R=0.25"). 
10-1  There are several candidates in the circle; the radio source may be the
10-1   sum of several of them. Adopted the brightest cluster (5981, V=19.63,
10-1   V-I=0.27, R=0.36"). 
11-2  Near the very bright region S (8191, V=17.60, V-I=0.30, R=1.08"), but have
11-2   adopted object 6665 (V=20.04, V-I=-0.15, R=0.40") since it is much closer
11-2   to the radio position and is a stronger H source. 
13-7  Two roughly equal candidates. Adopted 11623 (V=20.82, V-I=0.63, R=0.46") 
13-7  since it is slightly brighter than 11584 (V=21.20, V-I=0.73, R=0.48").
