II/221A             The LF Survey                         (McCuskey+ 1949-1959)

The Luminosity Function (LF) Catalogue (LF1 to LF9) McCuskey S.W., Seyfert C.K., Westerlund B., Annear P.R., Nassau J.J., van Albada G.B., MacRae D.A., Farnsworth A.H. <Astrophys. J. and Suppl. Ser. (13 publications in period 1949-1959)> Coordinates and Identifications of the LF Stars Skiff, B. <Unpublished (1994-2005)>
ADC_Keywords: Photometry, infrared ; Photometry, photographic 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), 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). Includes also cross-identifications with IRAS (II/215) and MSX (V/114) * 09-Aug-2007: Star LF 7 +40 479, by B. Skiff.
