Notes:
* The original file is in TeX form with a macro file. Conversion from
TeX to ASCII form is made by H.Andernach.
* The number of entries of table1 is 176 because a cD galaxy NGC4874
is included after the brightest cluster elliptical of A1656 (see paper
p1576).
* "BCE" stands for "brightest cluster elliptical(s)".

Byte-by-byte Description of file: table1
--------------------------------------------------------------------------------
Bytes Format Unit Label Explanation
--------------------------------------------------------------------------------
1 A1 --- NGC [N] 'N' denotes that the following number is
of NGC; in other case (' '), is of Abell
2- 5 I4 --- ABELL [0,] Abell cluster number
* If NGC='N' then NGC number
7- 13 F7.4 --- Z redshift of the BCE
16- 19 F4.2 arcsec SEEING [0,] FWHM of the seeing in the CCD image
22- 25 F4.2 --- E4 [0,1]? ellipticity for semimajor axis of
4 kpc
* Blank space means the BCE was not
observed at that radius, or the isophoto
was discarded (see paper p1576r)
28- 31 F4.2 --- E16 [0,1]? above of 16 kpc
34- 37 F4.2 --- E64 [0,1]? above of 64 kpc
40- 42 I3 deg PA4 [0,360[? position angle of the major-axis
of 4 kpc (see E4 above)
45- 47 I3 deg PA16 [-8/352]? above of 16 kpc
50- 52 I3 deg PA64 [0,360[? above of 64 kpc
54- 57 A4 --- decr_E [cpxe"~<>0 ] if ellipticity decreasing
outwards anywhere in its profile:
e" = 2nd outward derivative of E,
∼ = nearly equal, cpx = complex
59 A1 --- const_E [Y] 'Y' denotes constant ellipticity
61 A1 --- TWIST [Y] 'Y' denotes significant isophoto
twisting
63 A1 --- ASYM [Y] 'Y' denotes significant asymmetry
