Amigas Latinas Motivando el ALMA (ALMA)

Amigas Latinas Motivando el ALMA (ALMA): Development and Pilot Implementation of a Stress Reduction Promotora Intervention.

Use of mental health care services for psychological distress is limited among Latino immigrants. In geographic areas where migration has been rapid, mental health systems possess limited capacity to provide bilingual and bicultural assistance. The development of a bilingual and bicultural workforce is a necessary yet long-term solution. More immediate strategies, however, are needed to meet th...

ALMA Chapter 3.1: Calibration issues for ALMA

The precision imaging to be attained by the ALMA will be achieved through accurate calibration. The types of calibration are summarized in Table 3.1. Table 3.1 ALMA Calibration Requirements. Pointing 0.6" absolute Primary Beam 2-3% Baseline Determination 0.1 mm Flux Calibration 1% absolute flux accuracy goal Phase Calibration 0.15 radian at 230 GHz Bandpass Calibration 10000:1 to 100000:1 Polar...

ALMA Memo XXX Bandpass Calibration for ALMA

This memo contains a detailed evaluation of the expected performance of the bandpass calibration for ALMA. We evaluate the limitations on the bandpass accuracy due to the imperfect knowledge of the atmospheric transmission. We show that the best bandpass accuracy is obtained when the amplitude calibration is applied in a single-load scheme. The proposed scheme is a variant of the so-called band...

ALMA Memo 493 Finding Fast Switching Calibrators for ALMA

In order to perform fast switching phase calibration effectively, we need to have a database of bright point-like sources at millimeter wavelengths. Optimally, this would include flux measurements at 86 GHz and spectral information at higher frequencies. We present a sample of 31145 compact flat spectrum radio sources with −40 < δ < +60, presumed extragalactic, which will be likely candidates f...
