colimchain (colimchain-1.9) [xmmsas_20211130_0941-20.0.0]


colimchain is a perl task which is intended to facilitate the production of colour images from pipeline products. The user supplies colimchain with the location of the products, the instrument and the sequence of energy bands desired and colimchain does the rest. Smoothing via asmooth can be applied if the parameter smooth is set. In this case each of the input images is smoothed using the same template and mask, the smoothed images then being used as input to colimplot. If smoothing is not desired, colimchain supplies colimplot with the raw images. However, if no smoothing is desired, there is not much to be gained by using colimchain rather than colimplot directly.

A limited set of parameters from asmooth and colimplot have been provided. These are simply piped through to the corresponding parameters of the respective tasks. The task documentation for these tasks should be consulted for further description of the function of these parameters.

It is intended eventually to expand the task to accept OM images but this has not yet been done.
