For observations type 0, alpha and delta are given in degees to 6 decimal places. For type 1, Delta alpha, Delta delta are given in seconds of arc to 3 decimal places. Type 2 are similar to type 1 exept Delta alpha is in seconds of time. For type 3 obsrvations the position angle, P, is in degrees measured eastwards from north. The separation, S, is in secons of arc. Both P and S are given to 3 decimal places. evaluation: Residuals are given for X, Y in seconds of arc. For absolute and differetial coordinates and for position angle the residual is converted to residual in X, Y. The value 0.0 may be given if the residual were not computed. Any residual greater than 2.0 seconds of arc is given as 99.9 . Format. 1. Column 1- 3. Opposition number (1 - 1874, 112 - 1989) 2. Column 5- 8. Year of observation 3. Column 10-11.
