(1980s Hale-telescope quasar searches using new technology)
I use the name Palomar high-redshift quasar surveys for a
series of surveys outlined in a series of 1980s-1990s
papers with titles beginning "Spectroscopic CCD Surveys for
Quasars at Large Redshift".
The surveys were to find such quasars using the
Hale Telescope with at-the-time leading-edge technology, e.g., incorporating
CCDs. Various instrument combinations were used for the
individual surveys.
The surveys shared the designator prefix, PC.
(Explanations of the abbreviation PC are rare and inconsistent:
I've seen Palomar confirmed and Palomar calibrated.)
Survey names as per the published paper titles:
PFUEI (for "Prime Focus Universal Extragalactic Instrument")
was a Hale telescope instrument at the time.
The phrase "transit survey" was used differently than what
is now a common usage: currently the phrase is often used for a search
for extra-solar planet transits, but in this earlier case, transit
was used to mean a source passing through the field of view (i.e., like
a drift scan), a method used to discover quasar candidates.
