FourStar Reduction - FSRED

DATE link NOTES
Jul-11-2025 Now available in two virtual machines: an Intel-based VM for most Linux users and an Arm-based VM for Apple silicon users.

FSRED runs under either of these virtual machines, which have all the required 3rd party software installed. The latest version (OBSVM9 1.4 and OBSVM9arm 1.7) fix a number of bugs, including the old CDS star catalog server no loger being supported.

Mar-28-2022 Now available in the Observatories Virtual Machine

Due to the increased security measures taken by Apple in the latest versions of MacOS (11.1+), FSRED can no longer be supported natively on Macs. Alternatively, you can install the Observatories Virtual Machine (VM), a self-contained Linux OS that can be run on intel-based MacOS, Windows, or Linux computers. For Macs with Apple silicon (M1) chips, we hope to have a solution in the near future.

For assistance with the VM or the pipeline, please contact Chris Burns.

Jun-20-2013 FSRED.tar.gz

(1.07GB) Full FSRED package including archival data and supplementary material. install by:

tar -xvf FSRED.tar.gz -C ~
cd ~/FSRED
./install.csh

where ~ can be any preferred directory.

Jun-20-2013 FSRED.bin.tar.gz

(16MB) Updates to FSRED scripts. install by:

tar -xvf FSRED.bin.tar.gz -C ~
cd ~/FSRED
./install.csh

where ~ is the same as above (if not the home directory).

This is a set of .csh scripts which call IRAF tasks by supplying IRAF "param" files. There are a few custom C programs which use the CFITSIO and GSL libraries to handle the high density data and multi-extension fits format. The scripts also make calls to SExtractor/SCAMP/SWARP for astrometric alignment and resampling purposes.

 

Jun-20-2013 - Introduced .config file to allow parameters to be set outside the main fsred.csh script. New template.csh and template.config files for reducing data on a night by night basis. Edit the template.csh file to the correct datapaths and dates/filters of the desired data. template.config contains typical default values but can be edited as needed.
