Reduction and analysis tools for LMT/B4R
## Installation
```shell
pip install b4r==2024.7.0
```
## Usage
### Reduce individual data
```python
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`.
### Reduce all data (for database)
```python
import b4r.pipe as Bp
Bp.globBaseDir = '/home/hoge/b4r'
Bp.globLogDir = '/home/hoge/b4r/logv1'
Bp.PipelineAnalysisBatchRun()
```
You need to specify following pathes.
#### b4r.pipe.globBaseDir
- 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.
#### b4r.pipe.globLogDir
- The path where outputs are created.
- Anywhere you like is OK.
## Products
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)
## Correspondence
B4R 2018/2019 (obsnum<=087433) data <-> CASA MS2:
| Name | B4R | CASA MS2 |
| --- | --- | --- |
| polarization | A | (correlation or stokes) YY |
| polarization | B | (correlation or stokes) XX |
| sideband | LSB | spw 0 |
