Abstract:
I collect virtually all photometry of the 10 known galactic recurrent
novae (RNe) and their 37 known eruptions. This consists of my modern
measures of nearly all archival plates (providing the only data for
half of 37 known eruptions), my own 10000 CCD magnitudes from 1987 to
present (providing virtually all of the magnitudes in quiescence for
seven RNe), over 140000 visual magnitude estimates recorded by
amateur astronomers (who discovered half the known eruptions), and the
small scattering of magnitudes from all the literature. From this, I
produce various uniform products: (1) BVRIJHK comparison star
magnitudes and BV comparison star sequences to cover the entire range
of eruption; (2) complete light curves for all eruptions; (3) best-fit
B and V light curve templates; (4) orbital periods for all but one RN;
(5) exhaustive searches for all missed eruptions; (6) measured
discovery efficiencies since 1890; (7) true recurrence time scales;
(8) predicted next eruption dates; (9) variations on time scales of
minutes, hours, days, months, years, decades, and century;
(10) uniform distances and extinctions to all RNe; (11) BV colors at peak
and UBVRIJHK colors at minimum, all with extinction corrections; and
(12) the spectral energy distributions over UBVRIJHK. Highlights of
this work include the discoveries of one new RN, six previously
unknown eruptions, and the orbital periods for half the RNe. The goal
of this work is to provide uniform demographics for answering
questions like the "What is the death rate of RNe in our Galaxy?" and
"Are the white dwarfs gaining or losing mass over each eruption
cycle?." An important use of this work is for the question of whether
RNe can be the progenitors of Type Ia supernovae.

Note (1): My star names are just sequential letters, with a few small gaps
because some stars in the series were later identified as being
possibly variable or otherwise unsuitable. The positions (in the next
column) are accurate to roughly 1" and are useful for the unique
identification of the star.
I have created two sets of comparison stars for each RN. The first set
is three faint stars near to the RN, which I have measured in the
bands BVRIJHK. These stars are designated as "Comp" (typically a few
magnitudes brighter than the normal quiescent magnitude for the RN),
"Check" (typically close to the quiescent RN in both position and
magnitude), and "Check2."
