Features and Benefits: Digital readout of elevation - not only will high or low arrows be displayed, but the exact distance from grade will be numerically displayed, which eliminates the need to get "on-grade" to make measurements. The HL700 can be used as either a hand-held or rod mounted receiver for a wide range of applications. The HL700 offers a 3-year "No Excuses" warranty. The Laserometer is designed to survive the tough construction site conditions it is totally waterproof and can withstand a drop of 3 meters (10 feet) onto concrete. An anti-strobe sensor prevents false readings from site strobe lights. A 12.7 cm (5 inch) reception height, more than double the industry standard, allows quick acquisition of the laser beam. Selectable units of measure can be displayed meeting your application - mm, cm, ft, in or fractional inches. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity.

The readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from on-grade. The HL700 features a digital readout of elevation that provides a numeric display of +/- 5 cm (+/- 2 inches). The HL700 is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. Finally, we show that analyses of upcoming data will require Einstein-Boltzmann codes to be run with much higher numerical precision settings than is currently standard, so as to avoid similar- or larger-parameter biases due to inaccurate theoretical predictions.Spectra Precision Laser HL700 Laserometer Highly versatile receiver for basic and advanced leveling and aligning applications HL700 The Spectra Precision® Laser HL700 Laserometer, a highly versatile laser receiver for basic and advanced leveling and aligning applications, is designed for general, concrete and site preparation contractors. We also discuss an alternative, data-driven mitigation strategy based on delensing the CMB T and E-mode maps. We show that these biases can be mitigated by explicitly discarding all T T data at ℓ > 3000 or by marginalizing over parameters describing baryonic feedback processes, both at the cost of slightly larger error bars. For CMB-S4, the biases can be as large as 1.6 σ on the Hubble constant H 0 in a fit to Λ CDM and 1.2 σ on N eff in a fit to Λ CDM + N eff. Here, we show that inaccuracies in the modeling of C L κ κ can yield surprisingly large biases on cosmological parameters inferred from the lensed CMB power spectra measured by the upcoming Simons Observatory and CMB-S4 experiments. Thus, the high- ℓ (lensed) CMB is sensitive to these late-time, nonlinear effects. While these modes still carry primordial information, their theoretical modeling requires knowledge of the CMB lensing convergence power spectrum, C L κ κ, including on small scales where it is affected by nonlinear gravitational evolution and baryonic feedback processes.

However, at multipoles ℓ ≳ 3000, the CMB power spectra receive significant contributions from gravitational lensing. Upcoming measurements of the small-scale primary cosmic microwave background (CMB) temperature and polarization power spectra ( T T / T E / E E) are anticipated to yield transformative constraints on new physics, including the effective number of relativistic species in the early universe ( N eff).
