Individual studies, spanning a time baseline of up to 30 years, are self-consistently phased to produce light curves in 10 photometric bands covering the wavelength range from 0.4 to 4.5 microns. Data smoothing via the GLOESS technique is described and applied to generate high-fidelity light curves, from which mean magnitudes, amplitudes, rise times, and times of minimum and maximum light are derived. 60000 observations were acquired using the new robotic Three-hundred MilliMeter Telescope (TMMT), which was first deployed at the Carnegie Observatories in Pasadena, CA, and is now permanently installed and operating at Las Campanas Observatory in Chile. We provide a full description of the TMMT hardware, software, and data reduction pipeline. Archival photometry contributed approximately 31000 observations. Photometric data are given in the standard Johnson UBV, Kron-Cousins RCIC, 2MASS JHK, and Spitzer [3.6] and [4.5] bandpasses. Description: The Three-hundred MilliMeter Telescope (TMMT) is a fully robotic, 300mm telescope at Las Campanas Observatory (LCO), for which the nightly operation and data processing have been completely automated. Over the course of two years data were collected on 179 individual nights for our sample of the 55 RR Lyrae in the B, V, and IC broadband filters. Of these nights, 76 were under photometric conditions and calibrated directly. The 103 nonphotometric nights were roughly calibrated by using the default transformation equations, but only provide differential photometry relative to the calibrated frames. This resulted in 59698 final individual observations. Individual data points have a typical photometric precision of 0.02mag. The statistical error falls rapidly with hundreds of observations, with the zero-point uncertainties being the largest source of uncertainty in the final reported mean magnitude. To compare the results of our TMMT campaign to previous studies of these RR Lyrae (RRL) and to fill gaps in our TMMT phase coverage, we have compiled available broadband data from literature published over the past 30 years and spanning our full wavelength coverage (0.4 to 4.5µm) from the optical to mid-infrared. We have homogenized these diverse data sets to the following filter systems: Johnson UBV, Kron-Cousins RI, 2MASS J,H,Ks, and Spitzer [3.6], [4.5]. The All Sky Automated Survey (ASAS; is a long-term project monitoring all stars brighter than V∼14mag. The program covers both hemispheres, with telescopes at Las Campanas Observatory in Chile and Haleakala on Maui, both of which provide simultaneous I and V photometry. The GEOS RR Lyr Survey ( is a long-term program utilizing TAROT ( at Calern Observatory (Nice University, France). Annual data releases from this project add times for maximum light for program stars over the last year of observations. In addition to the large programs previously described, we use optical data from individual studies over the past 30 years (Barnes et al. 1992PASP..104..514B, Cacciari et al. 1987A&AS...69..135C, Skillen et al. 1993SAAOC..15...90S, Liu & Janes 1989ApJS...69..593L, Paczynski 1965AcA....15..115P, Jones et al. 1992ApJ...386..646J, Warren 1966MNSSA..25..103W, Fernley et al. 1989MNRAS.236..447F, Fernley et al. 1990MNRAS.242..685F, and Clementini et al. 2000AJ....120.2054C).

The mid-infrared [3.6] and [4.5] observations were taken using Spitzer/IRAC as part of the Warm-Spitzer Exploration Science Carnegie RR Lyrae Program (CRRP; PID 90002, Freedman et al. 2012sptz.prop90002F). WISE (Wright et al. 2010AJ....140.1868W; see also Cutri et al. 2012, Cat. II/311) or NEOWISE (Mainzer et al. 2011ApJ...731...53M, Mainzer et al. 2014, Cat.

Note (1): Mean magnitudes were determined by computing the mean intensity of the evenly sampled GLOESS fit points to the light curve, then converting back to a magnitude. The light curve must be sampled with enough data points to capture all the nuances of the shape for an accurate mean; in our case we sampled with 256 data points spaced every 1/256 in phase. Generally, GLOESS fits were determined only for those stars and bands that had more than 20 individual data points over a reasonable portion of phase (i.e., 20 data points only spanning Φ∼0.1 would not have a GLOESS fit nor a mean magnitude).

Note (4): The random uncertainty of the Gaussian-windowed LOcal regrESSion (GLOESS)-derived mean magnitude is simply the error on the mean of data points going into GLOESS fitting. Thus, stars with more data points will have a smaller uncertainty in GLOESS mean magnitude. The systematic uncertainty is determined by the photometric transformations, either in transforming our Three-hundred MilliMeter Telescope (TMMT) photometry onto an absolute system (see Figure 2) or as reported in the literature and in transforming from other filter systems (as described in Section 4). The final reported error is: σ2=1/∑(1/σ2phot)+1/∑(1/σ2sys), where the sum over σsys includes only the unique entries from each reference, i.e., it is not counted for every measurement.
