Mary, Dionne, and Alma

Abstract

The second of three chapters on the power of chocolate cities, this chapter centers the lives, activism, and pioneering efforts of three black women professionals, entertainers, and community activists: Mary Hill Sanders, Dionne Warwick, and Alma Burrell. Exploring their lives, health setbacks, and push against the glass ceiling and racial oppression, the authors highlight their sophisticated and politically informed racial geography of the United States. Detailing the movement of black people throughout the domestic diaspora, this chapter illustrates the how gender, place, race, and power collided in the lives of black people before and after the civil rights movement.

Telluric absorption lines in the ALMA spectra of η Car

“…We can see that the differences in ele v ation between the bandpass calibrators and the target were 14 • , 22 • , and only 2 • on 2015.3, 2016.8, and 2017.9, respectively. Therefore, at least on the last epoch we would not expect to find the contamination related by (Hunter et al 2018 ).…”

“…Since many molecules were detected at different wavelengths, it was not surprising that we started to see molecular absorption at ALMA frequencies (Smith, Ginsburg & Bally 2018 ;Bordiu & Rizzo 2019 ;Morris et al 2020 ). Ho we ver, a recent ALMA report (Hunter et al 2018 ) showed that sometimes telluric lines are not entirely remo v ed from the final spectrum, appearing as absorption features. Therefore, some additional analysis is required to recognize if an absorption feature is intrinsic to the source and not an artificial feature due to a calibration problem.…”

“…Therefore, some additional analysis is required to recognize if an absorption feature is intrinsic to the source and not an artificial feature due to a calibration problem. Hunter et al ( 2018 ) explained that telluric lines like ozone could still be present as a feature in the science spectrum due to an unperfect correction of the line emission during the atmospheric calibration. Since the atmospheric calibration is performed in a low-resolution spectral mode using 128 channels of 15.625 MHz, the core emission of a few atmospheric lines is eventually not resolved.…”
