# List of all Input Parameters
The example input file [input_sodankyla_example.yml](https://gitlab.eudat.eu/coccon-kit/proffastpylot/-/blob/master/example/input_sodankyla_example.yml)
contains the most relevant input parameters to run the PROFFASTpylot.
However, there are several more parameters which can be used optionally.
In this file all parameters are given and explained.
## Site information
- **instrument_number**
The serial number of your EM27/SUN.
- **site_name**
The name of the current measurement site.
- **site_abbrev**
A two-letter abbreviation to assign your site to a map file.
- **coords**
Coordinates of the measurement. Alternatively, a coordinate file can be used (see below).
- **lat**: Latitude, degrees north in decimal format
- **lon**: Longitude, degrees east in decimal format
- **alt**: Altitude, km over sea level
- **coord_file**
Give the coordinates in a comma separated file. An example file can be found in `examples/input_data/coords.csv`
- **utc_offset**
The UTC-offset of your measurements. This can either be due to
the measurement in a different time zone or due to an error in
the syncing of the PC clock.
- **note**
Optional comment included in bin-files by PROFFAST preprocess.
## Steering of the behavior:
- **min_interferogram_size**
File size in MegaBytes. All interferograms smaller than the given size are skipped.
- **igram_pattern**
The file name pattern of the interferograms
can be used to process only specific files in the interferogram folder.
The default value is `*.*` which means that all files in the
interferogram folders are used for processing.
- **start_with_spectra**
`True` or `False`
Start the processing chain with already available spectra.
The spectra have to be located at `/SiteName_InstrumentNumber/YYMMDD/cal`
where `` is the given analysis path.
- **start_date**
Date with the format `YYYY-MM-DD`.
The first date to be processed. If not given, the earliest available date is the start date.
- **end_date**
Date with the format `YYYY-MM-DD`.
The last date to be processed. If not given, the latest available date is the end date.
- **delete_abscosbin_files**
`False` (default) or `True`
The `*abscos.bin` file contains the the simulation of the
atmosphere which is the result of the PROFFAST pcxs program.
Pcxs can then be skipped if the abscos files are present from a previous run.
If True the `*abscos.bin` will be removed after the run
otherwise they are kept in `prf/wrk_fast`.
If the abscos files are not deleted, the pT and VMR files are copied instead of moved to the result
folder in order to be present if pcxs is skipped in a following run.
- **delete_input_files**
`False` (default) or `True`
If False: The output of the PROFFAST programs will be moved to results folder.
- **instrument_parameters**
To evaluate EM27/SUN data this parameter does not have to be given explicitly.
Possible values are: `em27`(default), `tccon_ka_hr`, `tccon_ka_lr`, `tccon_default_hr`, `tccon_default_lr`, `invenio`, `vertex`, `ircube` or a path to an instrument-config file.
For more details refer to the **Instrument Parameters** article of the documentation.
- **mapfile_wetair_vmr**
default: `None` (determined during runtime)
_If you are using other mapfiles_ than the standard ggg2020 or ggg2014 files you can set if the columns are based on wet air (`True`) or dry air (`False`).
## Path settings
- **proffast_path**
The path pointing to the PROFFAST folder.
- **interferogram_path**
The path to the interferograms. The data structure must
be like `YYMMDD/YYMMDD*.XXX`
- **map_path**
The path pointing to the map files.
- **pressure_path**
The path pointing to the pressure data.
- **pressure_type_file**
The path pointing to the pressure setup file.
_For more explanation see the article about pressure input in the documentation._
- **analysis_path**
In the analysis path the spectra produced by preprocess are
written to. We recommend to call it analysis.
Within this folder the PROFFASTpylot will create a folder
structure like `analysis/SiteName_InstrumentNumber/YYMMDD.`
_Consult also the article about folder structure in the documentation._
- **result_path**
The merged results, the log files and optionally the input files
are written to the result path.
Within it, PROFFASTpylot will create a folder named
`SiteName_InstrumentNumber_StartDate-EndDate`.
