The MyMidiGui tools work with the MIA and EWS packages in the same IDL session, which requires the startup of both MIA and EWS, in this order. It is also required to copy the executables made my the MIA installation script in the directory software/FITS/c/bin to the directory where the EWS executables are kept,i.e. software/EWS/c/bin.
After extracting the tar file for MyMidiGui, there will be a startup file which should be edited for the proper paths. Then one starts MyMidiGui by typing idl startup. The GUI itself is then started at the IDL prompt by typing mymidigui.
MyMidiGui is a tool to support quick-look analysis of MIDI observations as part of Paranal science operations. Therefore, it has limited functionality which focuses on making simple data reduction commands available as GUI buttons.
The Observation button starts up GORGONZOLA, the MIDI file selector tool. Only select up to one acquisition file, fringe search file, and up to one combination of a fringe track file including two photometry files (i.e. photometry for beam A and B). The selection files will then be displayed in the GUI.
Using the Move and Delete buttons, one can move the selected files to a directory named moremididata or delete the files, respectively. In both cases, a confirmation is needed fo the execution of the task.
The analysis of the acquisition image is started with the Acquisition button which first runs chop_nod_phot, and then displays an additional GUI for an alternative view of the acquisition data.
Buttons exist to display ON nd OFF source averaged images,
as well as their differences. These buttons will start atv
(written by and courtesy of Aaron Barth), which displays the images
and allows limited image analysis.
Just a few functions shall be explained here. First, change the
mouse mode to ImExam and cick on the target. The following
photometry GUI will be displayed.
Click on Photometry Settings and in the following GUI select select Magnitudes and set the zero point to 11.1. This is an experimentally derived value so that the magnitudes displayed in the photometry GUI are cose to N-band values.
Most importantly, the Fringe track button will display
this GUI to run both the Heidelberg and Leiden packages in their
default modes, and without user interaction.
After either has run, buttons to the right provide additional
functionality such as displaying the xmdv GUI, or printing
the group delay and visibility plots of the Leiden reduction.
Finally, the photometry buttons display the same atv
window as discussed above, only this time with the
chopped photometric images as selected from the displayed
GUI.
