Description:
The LF program was initiated at the Warner and Swasey Observatory by
S.W. McCuskey for studies of the variations of the stellar luminosity
function (LF) in the Milky Way. The program originally presented in a
paper of July 1947 (1947ApJ...106....1M 1947ApJ...106....1M), proposes an observation of
selected Milky Way regions with the 24-36-inch Schmidt telescope of
the Warner and Swasey Observatory down to mpg=12.25; the observations
result in spectral classification, photographic and photored
magnitudes of a large number of stars. The original catalogues
contain annotated charts of the studied regions, and tables with the
spectral types and magnitudes.
The catalog included here is a compilation of 13 publications of this
program corresponding to the fields LF1 to LF9 (detailed references in
the "References" section below). It was prepared by Brian Skiff
(Lowell Observatory) over the period 1994-2003, and includes the
original data (with the exception of the "red index" colors too noisy
to be of use), with cross-identifications to modern catalogues like
the GSC (I/254) that give accurate J2000 positions; he also added
extensive notes.

Note (1): the positions were generally derived from the GSC (I/254) or
the AC2000 (I/247) catalogues; more specifically in LF1, rPos means:
U = UCAC2 (I/289)
T = Tycho-2 (I/259)
M = 2MASS (II/246)

History:
* 31-Dec-2003: The Catalog was prepared by Brian Skiff, over the
period 1994-2000. The cross-identifications were made with the GSC
(I/254) catalog, plus other IDs, particularly from the HDE (III/135,
III/182) and BD (I/122) catalogues. The LF1 parts were revised in
December 2003.
* 07-Feb-2005: Completion of the part LF3b-1 by B. Skiff.
(Nassau & van Albada, 1949ApJ...109..391N 1949ApJ...109..391N). Includes also
cross-identifications with IRAS (II/215) and MSX (V/114)
* 09-Aug-2007: Star LF 7 +40 479, by B. Skiff.
