Table 7: The Qualifying Remarks Listed in Columns 16 and 17 of Table 4

DP = dirty picture    Dust specks or dirt are evident on the 
                      finding chart.

PD = plate defect     This can be on the PSS plate, the 35mm
                      negative or the finding chart print.

LP = light picture    The print of the finding chart is somewhat 
                      overexposed but the grains of the PSS plate 
                      are visible.

VLP = very light picture  The print of the finding chart is very
                          overexposed.  The grains of the PSS
                          plate are barely visible.

CH = crosshairs       The finding chart has closed rather
                      than open crosshairs.

CF = crowded field   

OF = obscured field    The field within the 4.14" search radius is 
                       partially obscured.

TABLE 8: The Group Classifications Listed in Column 16

--------------------------------------------------------------------
Character |  Optical Characteristics of the Identifications in Groups
--------------------------------------------------------------------
first      B = Brightest member
           M = member
second     C = Compact group.  The galaxies are separated by
               only a few galaxy diameters.
           M = Medium compact group. The galaxies are separated 
               by about 5 to 10 galaxy diameters.
third      1 = one first ranked galaxy.
           2 = two approximately equal magnitude
               first ranked galaxies.
           3 = three or more approximately equal magnitude
               first ranked galaxies.
fourth     S = small group, 5 galaxies.
           M = medium group, 5 to 10 galaxies.
           L = large group,   >   10 galaxies. 
           C = cluster,      >>   10 galaxies.

TABLE 9: The Symbols Used in Column 19

Identifications Within 2 Arcmin of Known Clusters of Galaxies

The letter preceding the cluster catalog number:
a = Abell Cluster       z = Zwicky Cluster

The notations following the catalog number:
cc = at cluster center    
nc = not at cluster center
mc = near cluster center
ni = not identified with probable cluster member
c: = cluster not obvious on finding chart
ef = identification is EF (empty field)
=============================================================
Identifications From Veron-Cetty & Veron or Wills & Wills
v = Identification from Veron-Cetty and Veron (1983)
w = Identification from Wills and Wills (unpublished) 

Followed by one or more of the symbols listed below:
q = Identification is probably a QSO or BL Lac Object
g = Identification is probably a galaxy
z = Identification is confirmed by spectrum giving redshift
s = Identification is confirmed to be a star
e = Veron-Cetty & Veron list an empty field at the source position
x = For Veron-Cetty & Veron, I disagree with the identification
: = For Veron-Cetty & Veron, the agreement with the TS
       identification is questionable
: = For Wills and Wills, the spectroscopic data suggests
       but does not confirm the identification
