The Large Synoptic Survey Telescope (LSST) will be the largest time-domain photometric survey ever. In order to maximize the LSST science yield for a broad array of transient stellar phenomena, it is necessary to optimize the survey cadence, coverage, and depth via quantitative metrics that are specifically designed to characterize the time-domain behavior of various types of stellar transients. In this paper, we present three such metrics built on the LSST Metric Analysis Framework model. Two… 
A Higher Cadence Subsurvey Located in the Galactic Plane
Presently, the Galactic plane receives relatively few observations compared to most of the LSST footprint. While this may address static science, the plane will also represent the highest density of
The Large Synoptic Survey Telescope: A summary update on the scientific potential for pulsating star research
The Large Synoptic Survey Telescope (LSST) will provide hundreds of deep images of the southern sky over its 10 year duration, enabling variability studies for an unprecedentedly large and unbiased


An end-to-end simulation framework for the Large Synoptic Survey Telescope
The development, and use of the LSST simulation framework is described, including the generation of simulated catalogs and images for targeted trade studies, simulations of the observing cadence of theLSST, the creation of large-scale simulations that test the procedures for data calibration, and the use of end-to-end image simulations to evaluate the performance of the system as a whole.
Star counts in the Galaxy - Simulating from very deep to very shallow photometric surveys with the TRILEGAL code
We describe TRILEGAL, a new populations synthesis code for simulating the stellar photometry of any Galaxy field. The code attempts to improve upon several technical aspects of star count models, by:
Stellar SEDs from 0.3 to 2.5 μm: Tracing the Stellar Locus and Searching for Color Outliers in the SDSS and 2MASS
The Sloan Digital Sky Survey (SDSS) and Two Micron All Sky Survey (2MASS) are rich resources for studying stellar astrophysics and the structure and formation history of the Galaxy. As new surveys
The Milky Way Tomography with SDSS
Using the photometric parallax method, we estimate the distances to {approx}48 million stars detected by the Sloan Digital Sky Survey (SDSS), and map their three-dimensional number density
The UKIRT wide field camera ZYJHK photometric system: calibration from 2MASS
In this paper, we describe the photometric calibration of data taken with the near-infrared Wide Field Camera (WFCAM) on the United Kingdom Infrared Telescope (UKIRT). The broad-band ZYJHK data are
The Galactic Distribution of Asymptotic Giant Branch Stars
We study the Galactic distribution of ∼10 000 candidate asymptotic giant branch (AGB) stars selected by IRAS colours and variability index. The distance to each star is estimated by assuming a narrow
Studies in astronomical time series analysis. III - Fourier transforms, autocorrelation functions, and cross-correlation functions of unevenly spaced data
Techniques for removing the distortion of the correlation functions caused by the sampling, determining the value of a constant component to the data, and treating unequally weighted data are discussed.
Least-squares frequency analysis of unequally spaced data
The statistical properties of least-squares frequency analysis of unequally spaced data are examined. It is shown that, in the least-squares spectrum of gaussian noise, the reduction in the sum of
