DESHIMA merge code for observed datasets

Installation

shell pip install demerge==2025.8.4

Command line interface

de:merge ships with three commands, demerge, reduce, and merge. demerge is the main command that (1) reduces raw data of KID measurements into a single "reduced" FITS and (2) merge datasets of a DESHIMA observation (including the reduced FITS) into a single DEMS file. reduce and merge are the subcommands that perform (1) and (2), respectively, and they should be used only for debugging.

Here is (part of) the demerge command help: ```plaintext SYNOPSIS demerge OBSID

DESCRIPTION Run reduce and merge commands to create a single DEMS.

POSITIONAL ARGUMENTS OBSID Type: str Observation ID (YYYYMMDDHHMMSS).

FLAGS --datadir=DATADIR Type: Path Default: PosixPath('.') Path of directory where data packages are placed, i.e. expecting ${data_dir}/cosmos_YYYYMMDDHHMMSS. --demsdir=DEMSDIR Type: Path Default: PosixPath('.') Path of directory where merged DEMS will be placed, i.e. expecting ${dems_dir}/dems_YYYYMMDDHHMMSS.zarr.zip. --reduceddir=REDUCEDDIR Type: Path Default: PosixPath('.') Path of directory where reduced packages are placed, i.e. expecting ${reduced_dir}/reduced_YYYYMMDDHHMMSS. If not specified, a temporary directory will be used. --cdb=CDB Type: Path Default: PosixPath('/path/to/demerge/data/cdb20250528.zarr.zip') Path of CDB (KID correspondence database) file. --ddb=DDB Type: Path Default: PosixPath('/path/to/demerge/data/ddb20250819.fits.gz') Path of DDB (DESHIMA database) file. --overwrite=OVERWRITE Type: bool Default: False If True, the reduced package and the merged DEMS file will be overwritten even if they exist. --debug=DEBUG Type: bool Default: False If True, detailed logs for debugging will be printed. ```

A typical command run is as follows: shell demerge YYYYMMDDHHMMSS --data_dir /path/to/data --reduced_dir .cache where the raw data directory, /path/to/data/cosmos_YYYYMMDDHHMMSS, will be selected, then an intermediate reduced data directory will be created as ./.cache/reduced_YYYYMMDDHHMMSS, and finally the merged DEMS file will be placed as ./dems_YYYYMMDDHHMMSS.zarr.zip.

Raw data directory

The name and the file structure of a raw data directory must be as follows:

plaintext cosmos_YYYYMMDDHHMMSS/ ├── YYYYMMDDHHMMSS.ant ├── YYYYMMDDHHMMSS.cabin ├── YYYYMMDDHHMMSS.fits ├── YYYYMMDDHHMMSS.misti ├── YYYYMMDDHHMMSS.obs ├── YYYYMMDDHHMMSS.skychopper.dat.xz ├── YYYYMMDDHHMMSS.wea ├── YYYYMMDDHHMMSS_info.txt ├── kid_corresp.json ├── kids.list ├── localsweep.sweep ├── localsweep_info.txt └── pretune ├── kids.list ├── localsweep.sweep └── localsweep_info.txt

If multiple files with the same extension exist, then the last one sorted by name will be selected.

Use as a Python package

All (sub)commands are also available as Python functions of the same names in the demerge package. For example, the following two runs are equivalent:

```shell

run by a shell script

demerge YYYYMMDDHHMMSS --datadir /path/to/data --reduceddir .cache ```

```python

run by a Python script

from demerge import demerge demerge("YYYYMMDDHHMMSS", datadir="/path/to/data", reduceddir=".cache") ```
