GPItv is a data viewer tool that provides GPI observers with both a simple means for cursory “quick look” data analysis, in real time at the telescope, and a sophisticated set of tools for viewing and manipulating GPI data during post-observing scientific analyses. GPItv includes features for spectral and polarimetric analyses of raw 2D and/or processed 3D data from GPI. GPItv should help you to look at GPI data in a way that enables you to get your science done.
GPItv is a heavily customized derivative from ATV, the well-known DS9-like display tool for astronomical images in IDL (Barth et al. 2001; http://www.physics.uci.edu/~barth/atv/), with much new functionality developed specifically for GPI. Anyone familiar with using ATV, SAOimage or DS9 will get used to GPItv very quickly.
One significant enhancement relative to the original ATV program is that GPItv’s internals have been rewritten to allow multiple copies to run simultaneously. Thus users can view for instance raw frames, reduced datacubes, and ADI-processed subtracted images all in separate windows simultaneously
GPItv is a display tool that includes features for image analysis and spectral analysis. 2D image analysis tools are available for image manipulation, including:
Spectral analysis tools include:
Polarimetric analysis tools include:
New features can be added to GPItv easily, including linking to or calling existing IDL programs. For example, you can easily define a keyboard shortcut that will pass the current cursor position in data coordinates to an external IDL routine.
