Data reduction for bolometer arrays

For data reduction of bolometer data (from the instruments LABOCA, SABOCA and ArTéMiS) we use at APEX the following software packages:


BoA (BOlometer Array Analysis Software)

BoA is a newly designed software package for the reading, handling, and analysis of bolometer array data. Its design and implementation is a collaborative effort of scientist at the MPIfR, AIfA, AIRUB, and IAS that was started in 2002. The primary goal of BoA is to handle data from LABOCA at APEX, both for online visualisation and offline processing. BoA can also be used to process data acquired with other instruments such as ASZCa at APEX or MAMBO at the IRAM 30-meter telescope. BoA includes most of the relevant functionalities of the current reduction packages (MOPSIC, NIC, SURF). The major difference to them is that BoA is written in a programming environment that is (hopefully) easier to modify, maintain, and re-use. Moreover, BoA naturally interface with APECS and the MBFITS format.

  • Reduction of LABOCA/SABOCA data with BoA by Frédéric Schuller. This document in the form of presentation should be used only as a guideline since some functionalities have evolved since this cookbook was first presented in 2008.
  • For historical reasons we leave here a guide on how to reduce LABOCA data collected in wobbler on-off mode (a.k.a. photometry mode).

  • We have collected the SABOCA array parameters and a few helper scripts to apply the correct RCP file as well as lists of bad and inverted channels, convenient for you to download. A template SABOCA reduction script is also included:

CRUSH 2

CRUSH-2 is the Comprehensive Reduction Utility for SHARC-II but can also reduce data for other bolometer arrays, as LABOCA, SABOCA, Artemis, ASZCa and polarisation data from PolKa. The software is released under version 3 of GNU General Public License GPLv3.

The software is maintained by the author, Attila Kovács at http://www.submm.caltech.edu/~sharc/crush/ where you can find and download the latest version of the software as well as extensive documentation.

Earlier versions of this software were called minicrush or CRUSH-1.xx, but these are now officially deprecated, and users are encouraged to use the latest version of CRUSH-2.

ArTéMiS pipeline in IDL

A dedicated data reduction pipeline running in IDL (Interactive Data Language) has been developed by the instrument team. You can download the IDL packages for ArTéMiS below:
