The PCOT cookbook

This is a repository of useful PCOT documents containing graphs for performing common tasks. If you don't know what PCOT is, please look here for more information. It also contains camera definition files.

Typically, the graphs are saved with some small images as example data. To use your own data, click on the input button at the top of the screen which corresponds to the input you want to replace (this is almost always input 0) and load the required input. You may need to ensure that your data has the bands the graph expects, or edit the graph accordingly.

You will probably have to edit the graph somewhat to produce the analysis you need, but these will give you a starting point from which to do that, as well as providing useful examples.

Analysis documents

These are (hopefully) the "bread and butter" of working with PCOT: loading data into PCOT documents which process it in a (more or less) obvious but at least clearly visible way.

• Plotting spectra of points
• False colour spectral parameter map
• Combined spectral parameter map

Calibration

These are scripts or documents which take raw data and process it into a form ready for analysis. The calibration pipeline is, roughly speaking, this:

flowchart LR
image[(image)] --> darkfield --> linearise --> flatfield --> Rstar[R*]

Calibration data prep. scripts

• Darkfield / flatfield preparation
