Description:
table1 is a compilation of the flux densities at 22.25MHz for 395
sources, derived from three or more observations of each source. The
source were measured over a period of several years with the T-shaped
radiotelescope at the Dominion Astrophysical Observatory. The
Note: This catalogue supersedes Cat. J/AJ/74/366

Note (1): the position was added by Trushkin (1998) with CATS
Note (2): the symbols have the following meaning:
C: a 26.3 MHz flux density measured at Clark Lake is given by
Viner and Erickson (1975AJ.....80..931V 1975AJ.....80..931V)
G1, G2, G3, G4: Low frequency flux densities measured at
Grakovo are given by Braude et al. (1978Ap&SS..54...37B 1978Ap&SS..54...37B,
1979Ap&SS..64...73B 1979Ap&SS..64...73B, 1981Ap&SS..74..409B 1981Ap&SS..74..409B, 1985Ap&SS.111..237B 1985Ap&SS.111..237B)
respectively.
1: See notes for this source in Roger et al. (1973AJ.....78.1030R 1973AJ.....78.1030R).
2: Comprises 3C66A and 3C66B and possibly a broad emission component.
3: Confusing sources surrounding 3C196 or emission from
broad region centered on the source: near Abell 637.
4: Transits 0.8 min earlier than 4C14.31, near right ascension
of Abell 795.
5: Evidence of E-W broadening.
6: Confused region; other sources not catalogued. Alternative
interpretation with source on broad background feature
gives a flux density of 128 ± 20 Jy.
7: Broad emission centred on 3C298 (∼50' EW).
8: Extended source, corrected for broadening.
9: Right ascension 45 sec later than listed in 4C (lobe shift ?).
10: Possibly extended.
11: Primary calibration source.
12: Confused region.
13: Epoch 1966.5.
