b4rpipe 0.0.9

Pipeline reduction tools for B4R (2mm heterodyne reciver) on LMT 50m @Mexico

b4rpipe

A pipeline reduction tool for B4R/LMT data.

The scripts are still under development. We are not responsible for the outputs now.

---

Installation

---

$ pip install b4rpipe

---

Usage

---

Reduce individual data

$ python
$ >>> import b4rpipe 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.

Reduce all data (for database)

$ python
$ >>> import b4rpipe as Bp
$ >>> Bp.globBaseDir = '/home/hoge/b4r'
$ >>> Bp.globLogDir = '/home/hoge/b4r/logv1'
$ >>> Bp.PipelineAnalysisBatchRun()

You need to specify following pathes.

b4pipe.globBaseDir

• The path where "xffts" and "lmttpm" directorys 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.

b4rpipe.globLogDir

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

The script create following outputs (if possible).

• Continuum Map Qlook (Pointing offset, efficiency, etc.)
• Line (SiO) Map Qlook (Pointing offset, etc.)
• Spectrum Qlook (with auto-flag)
• MS2 (CASA readable format)
