Description:
This catalog contains 1692 radio sources observed with the Penticton
synthesis telescope at 408 MHz and at 1420 MHz. The catalog is
comprised of sources detected in the P-surveys 1P through 9P, 12P
through 15P, and 20P through 27P (see the "References" section below).
The database was provided by R.Roger & C.R.Purton in May 1990 and an
update of the data with further P-surveys is currently in progress.

--------------------------------------------------------------------------------
Note (1): The 'PName' column gives the source name in the DRAO convention,
ie. a 2-digit P-survey number (DRAO table number), followed by a 'P'
and appended by the sequence number of the source within that survey.
The latter has a maximum of 3 digits and may be appended by a
component indicator like A, B, C.
Note (2): The positional errors are given in the 'e_RAs' column (in
seconds) and in the 'e_DEs' column (in arcsec). If the error columns
are blank, the error is unknown.
Note (3): The frequency (in MHz) at which the source was measured is given
in the freq column. It is either 408 or 1420 MHz. The flux density and
error are given in the 'fluxd' and 'e_fluxd' columns, both in mJy.
Note (4): This column gives a flag consisting of three numbers. The first
number indicates the type of position determination used to derive
right ascension and declination:
1 = rough estimate
2 = centroid
3 = peak
4 = fitted Gaussian
5 = unknown
The second number gives the type of flux reported, where
1 = total or integrated flux and
2 = peak flux.
The third number gives the type of flux determination for the flux
density as follows:
1 = sum of positive values above baselevel
2 = sum of values about baselevel
3 = fitted Gaussian
4 = unknown
Note (5): The major and minor half-power widths are given in 'fwhm_maj'
and 'fwhm_min' in units specified in the first digit of 'fwhm_flg'
(1=arcmin, 2=arcsec). The position angle is given in the 'pos_ang'
column in integer degrees. The position angle is sometimes positive,
sometimes negative, but always from N through E.
The second digit of the 'fwhm_flg' describes how the shape of the
radio source was determined:
1 = approximate diameter (minor width blank)
2 = fitted Gaussian
3 = unknown
The third digit of 'fwhm_flg' is a qualifier on the shape, where a
value of 1 means the source may be affected by delay beam and a blank
value means a reliable estimate.
Note (6): This column gives the observation date in decimal years.
Note (7): This column gives comments on the source or cross-identifications
with other surveys.

History:
(from the table "rad_drao" available at the "ADS Catalogue Service",
CfA, Harvard-Smithsonian Center for Astrophysics, Cambrigde MA)
The data were provided by R. Roger and C.R. Purton to H. Andernach in
May 1990, who reformatted them to one line per source in June 1993.
Each source now has one record in the database. The code for the
coordinate equinox was removed as ALL entries were in B1950.
The flux-unit-flag was removed as all fluxes were in mJy. The flag for
type-of-position was joined with those for the type-of-flux and type-
of-flux-determination in a single 3-digit string.
The columns for 'flux #2' were removed as they were all empty.
Position angles for 12P4, 13P11, 21P15,135,136,154 were converted to
integer degrees. The flags for width-unit and shape parameters were
also joined into one 3-digit string.
