Setting up multislit observations

Before the start of observing:

If you wish to run the quick-look analysis at the telescope, you should also do the following:

Setting up on your field

Instructions for setting up slitmasks, using icbox, ialign, and ifalign for the alignment, can be found in the IMACS Cookbook. If you have trouble identifying the alignment stars in the ialign window, the following procedure may be helpful:


Setting up IFU observations

Checking the IFU alignment

Because the images of each IFU fiber are very small, and adjacent fiber images are quite close together (only a few pixels with the short camera), very precise alignment is necessary for reliable image and spectral extraction. To check the IFU alignment, do the following:


Spectral extractions

If you have already performed the steps listed above to set-up for quick look reductions, then spectral extraction requires only the following steps:


Data reduction pipeline

A pipeline generator for 2-d data now exists; See process-2dspec.


Important Notes!

Please report all bugs to cosmos[at]ociw.edu, but please first make sure that you have carefully read the documentation and are using the software correctly.
