Positions, distances, absolute magnitudes and spectral types for misclassified pCNS3
stars south of declination -30o. The majority of these stars have
spectral characteristics inconsistent with the absolute magnitude assigned in pCNS3, in
most cases due to the distance being underestimated; the remaining
stars are white dwarfs. Many of the former stars
are from Wolley et al's (1970) extension of Gliese's CNS1.
The format is similar to Tables 1A and 1B, save that we list apparent magnitude in addition
to the inferred absolute magnitude. Positions from the following sources:
1. Co-ordinates measured at the Palomar 60-inch telescope
2. Co-ordinates measured at either the Palomar 200-inch telescope, Keck or the AAT
3. HST Guide Star catalogue (version 1)
4. pCNS3
5. Digital Sky Survey images.
6. Hipparcos
Most of the spectral types listed in this Table and in Table 1D are taken from SIMBAD.

C: spectral types suggest that these candidates companions are not associated with
the potential primary star.
Individual stars
NN 148 = Gl 32B: CNS3 lists V=8.41 and 9.06 for Gl 32A and 32B, respectively; Hipparcos gives
a parallax of 62.5+/-1.5 mas, r=16.0 pc, implying MV = 7.4 and 8.0, inconsistent with
spectral types. Apparent magnitudes underestimated?
NN 1224 - Gl 288B is the white dwarf van Biesbroeck 3
NN 1809 - Gl 432B is the white dwarf van Biesbroeck 4
NN 3662 - Gl 893.3A: MV estimated from Bessell's (1990) measurement of (V-I)=1.099
NN 3663 - Gl 893.3B: LP 1034-093, listed as cpm companion of Gl 893.3A, sep=19 arcsec, PA=160
A small number of M-dwarf candidates listed in the pCNS3 were not observed in the course of the PMSU survey. We list positions, distances, absolute magnitudes and spectral types for those stars here. Note that Gl 389A, Gl 389B and LHS 288 are listed mistakenly as K-type dwarfs in PMSU2. Denis-P J1048 was discovered after the compilation of the pCNS3.

NN 74 = Sm 177: Spectral type from Smethells (1974), MV based on (V-I) from
Reid (1982), but no star of that magnitude close to position given in the latter paper. The nearest
bright star is CD-41 226 (V=10.75, (B-V)=0.57)
NN 570 = Gl 127.1B: listed as 8" from Gl 127.1A with V=14.73, (B-V)=0.62 (Bessell, 1990). No such star
evident in our 1995 LCO observations, and colours are inconsistent with an M dwarf companion. Background
