Scans of the Palomar-Leiden Trojan Survey Plates
van Houten-Groeneveld, I.; van Houten, C.J.;
Wisse-Schouten, M.; Bardwell, C.; Gehrels, T.
This service publishes plate scans of the Palomar-Leiden Troian
surveys conducted between 1960 and 1977. The surveys led to the
discovery of more than 2,000 asteroids (1,800 with orbital information),
with another 2,400 asteroids, including 19 Trojans, found after further
analysis of the plates.
Note that because of the large size of the plates, in this service each
original plate is contained in two parts, marked with "_1" and "_2",
respectively. The central parts
of the two parts overlap.

Most exposures were made on Kodak 103a-O emulsion, with a WG2 filter.
One pair per field was taken each month on Kodak 103a-D emulsion,
using a Y-6 filter.
Best effort is made in this service to reliably identify
the emulsion and filter used in each exposure, but
plate metadata has been incomplete. Use the information with
caution.
