MOPSIC is a software which has been developed and is constantly upgraded by Robert Zylka (IRAM, France). It was created to analyze bolometer data but can be used for much more versatile tasks.
This cookbook is to help in the Mambo2 reduction with the pool. It is largely taken from the READMEs provided by the pool system when downloading the project data. It will give you as well some informations to setup your observations.
General Informations
Tar-file structure of a full download (dafs, scripts, software & data)
If you have downloaded MOPSIC together with the DAFs (Data Associated Files) and the MOPSIC scripts used at the telescope, the tar file will generate six directories:
dafs data logs mopsic scripts work
The dafs directory contains all calibration files and links needed by MOPSIC to calibrate your data. Zenith opacities, receiver channel (i.e. bolometer) parameters, bad receiver channels, flat-field for sky noise filtering and calibration factors are stored in MRT_MAMBO.TAUS, MRT_MAMBO_MB.RCP, MRT_MAMBO_PF.RCP, MRT_MAMBO.DRC, MRT_MAMBO.CSFF and MRT_MAMBO.CAL, ordered by the Julian Date or UT date.
The data directory contains all project observations (scans) as well as pointing, focus, calibration and skydips scans done within one hour from the target observations.
The logs directory contains a project summary listing all target and calibration scans. In mopsic you will find the MOPSIC executable (since June 15 2005 the f95 version).
The scripts directory contains all up-to-date MOPSIC scripts used in the database pipeline reduction (for details see below).
The work directory contains a listing (mydata.LIST) of all scans in the data directory. Such list are use by MOPSIC to find and list data for reduction. Furthermore the directory contains links to the MOPSIC scripts in the script directory. If you are using our standard installation of MOPSIC you should use this directory to reduce the data.
MOPSIC installation
System requirements:
- standard Linux system
- NEW GILDAS ifort version installation required (younger than Oct 18th 2005)
Installation: If you have downloaded together with the MOPSIC software the DAFs-files MOPSIC will know all parameters related to the bolometer array calibration such as the gain parameters, array geometry and the counts per Jansky conversion as well as the zenith optical depths for all data obtained in pooled observations since summer 2001 (the optical depths since Feb 1999). Older DAFs are available under request. We therefore recommend to download the DAFs and to update them regularly. In order to use these parameters on your local MOPSIC installation you have to define the system variable MOPSIC_DAFS by adding the following line to your .cshrc or .tcshrc system file:
setenv MOPSIC_DAFS /YOUR/DOWNLOAD/INSTALLATION/PATH/dafs
or to the.bashrc file:''
export MOPSIC_DAFS=/YOUR/DOWNLOAD/INSTALLATION/PATH/dafs
To run MOPSIC from all directories on your system you furthermore need to add to the same file the path where the MOPSIC executable is located:
in .cshrc or .tcshrc: Of course it is not mandatory to keep MOPSIC and the DAFs in the directories created by the tar. You may put them wherever you want. set path path=($path /YOUR/DOWNLOAD/INSTALLATION/PATH/mopsic)
or in .bashrc: PATH=$PATH:/YOUR/DOWNLOAD/INSTALLATION/PATH/mopsic
export PATH
