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 ~ 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 ~ 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.
