ADC_Keywords: Positional data ; Proper motions
Description:
The original plans for the Southern Yale Zone catalogs were to
reobserve and derive strengthened positions and proper motions for all
stars in the zones -30 deg to -50 deg and -60 deg to -90 deg. Having
been delayed by an incredible number of misfortunes, the zone -60 deg
to -70 deg has now been published (Fallon 1983). The catalog contains
the measured positions and derived proper motions for the stars in
this zone. In addition to the data in the published catalog, this file
lists the numbers of the plates measured for each star.

1- 5 I5 --- Number [1/14597]+ Serial number.
6- 13 A8 --- CPD [-0123456789 ]! Designation in the Cape
Photographic Durchmusterung (CPD,
Gill and Kapteyn 1896, Cat. I/108).
14- 15 I2 h RAh Right Ascension for Equinox 1950 (hours)
16- 17 I2 min RAm Right Ascension 1950 (minutes)
18- 23 F6.3 s RAs [0/60] Right Ascension 1950 (seconds)

27- 28 I2 arcmin DEm Declination 1950 (minutes)
29- 33 F5.2 arcsec DEs Declination 1950 (seconds)
34- 40 F7.2 yr Epoch [1941/1964] Epoch for position.
41- 47 F7.4 s/yr pmRAs []? Annual proper motion in RA
48- 53 F6.3 arcsec/yr pmRA []? Annual proper motion in RA (*cos(delta))
54- 59 F6.3 arcsec/yr pmDE []? Annual proper motion in DE
60- 63 F4.1 mag Mag [-1/19]? Visual magnitude.
64 A1 --- n_Mag *[*] An asterisk indicates constructed
magnitude.
65- 69 F5.2 mag CI *[-1/4]? Color index.
70- 71 I2 --- Images Number of images measured. A pair
of grating images is counted as one
image.
72- 73 I2 --- Plates Number of plates measured.
74-109 18I2 --- PlateList 18 two-digit numbers identifying
plates on which images were
measured. If the number measured
is less than 18, a zero fill is
used for blank fields.
110 I1 --- FieldCode *[0/1] Field star code.
111 A1 --- pmCode *[A-H] Proper motion code.

Note on n_Mag and CI:
See note in "adc.doc". Note however that the following stars
have very high magnitudes are variables or very late-type stars:
Magnitude 19.0 for stars
#1707 6181 7370 7883 8852 10606 11237 12261 12614 13157 13236 13868
Magnitude 18.8 for stars
#2091 5092
Note on FieldCode:
This code is always zero, meaning a standard reduction from
at least two overlapping plates.
See also note in "adc.doc".
Note on pmCode:
See detailed note in "adc.doc". Short explanations:
A = Proper motion taken directly from the CPC (therefore on FK3 system).
B = Proper motion Yale - LaPlata positions.
C = Same as B but mean from overlapping LaPlate positions
D = LaPlata position from NFK (Peters 1907)
E = Proper motion from Sydney - Yale plates
F = Proper motion from mean of Yale/Sydney compared with LaPlata.
G = not explained code; exists for stars #13513 13578 13684 13765 13791
#13814 14256 14257 14271 14299 14384 14411 14432 14470 14496 14497
H = not explained code; exists for star #13661

Document editing:
Nancy G. Roman [SSDOO/ADC] added the key words and description and
modified the format table slightly to correspond with the current
standard document on 20-Feb-1995.
