Appendix: COODINATES OF OBSERVATORIES

This list is the extension of Marsden's list of observatories published
in "Minor Planet Circularies". The additional data about observatories
were taken from other sources.

ATTENTION! These coordinates may be used for reduction of
routinal observations with standard accuracy. For reduction of high
accuracy observations (CCD, meridian obs., NEO objects) should be
used more exact coordinates of instrument.

-------|------------------------|---------------------------------------------
2- 5| Number of observation | The numbers 0-999 were taken in according
| | to Marsden (Ref.1), the numbers from 1000
| | were appropriated by us.
| |
7- 30| Location of observatory| Country, place, town
| |
32- 75| Name of observatory |
| and some notes |
| |
77- 85| Longitude | in angular units (dddmm.mm)
| |
87- 94| Geodetic latitude | in angular units (ddmm.m)
| |
96- 99| Height in meters | For observatories with numbers 0-999
| | and code of reference 1* the heights
| | were taken by maps
| |
101-103| Code of references | For numbers 0-999 the code equals 1 usually.
| | It should be noted that in many cases
| | the heights were obtained unreal from
| | Marsden's data. So the coordinates of obs.
| | from MPC were improved by us from other
| | sources and the code of these observatories
| | was noted by the asteriks (1*).
