Reduction and analysis tools for LMT/B4R

pip install b4r==2024.7.0

import b4r.pipe as Bp


Bp.globBaseDir = '/home/hoge/b4r'
Bp.globLogDir = '/home/hoge/b4r/logv1'
Bp.PipelineAnalysis(86420)

This example shows a pipeline analysis for the data obsid 86420.

import b4r.pipe as Bp

Bp.globBaseDir = '/home/hoge/b4r'
Bp.globLogDir = '/home/hoge/b4r/logv1'
Bp.PipelineAnalysisBatchRun()

You need to specify following pathes.

• The path where xffts and lmttpm directories are located.
• XFFTS binary data (e.g., xffts20181003111006.xfftsx.01) should be stored under the xffts directory.
• LMT antenna log data (e.g., lmttpm_2018-04-22_075858_01_0000.nc) should be stored under the lmttpm directory.

• The path where outputs are created.
• Anywhere you like is OK.

The script create following outputs (if possible).

• Continuum Map Qlook (Pointing offset, efficiency (only for uranus), etc.)
• Line (SiO) Map Qlook (Pointing offset, etc.)
• Spectrum Qlook (with auto-flag)
• Time series spectrum of PSW data (NumPy readable format)
• GoDec calibration results (see Taniguchi et al. 2021)
• MS2 (CASA readable format)
