A wrapper for the (OTW) midoq.sh that lets you query a single record from the *.info file associated with a local FITS image. If you send this routine a record number of "0", then it simply returns the total number of apertures contained in the *.info file. Also, recall that midoq.sh is not particularly useful by itself. It serves as a simple template code that demonstrates how to access the mido (Measure IDentified Objects) in a more complicate code that might might numerically manipulate the image parameters further. For example of this, see the midophotcat.sh which enables the user to create table and cdfp files that contain calibrated photometric parameters (i.e. aperture magnitudes and sky surface brightness values) along with astrometric positions from the image WCS (in the header).

A lot of text here would serve little purpose. If you really want to see how this code works, read the documentation for midoq.sh. Finally, if you want an overall view of how to create the *.info file and perform various tasks, see my Image Statistics documentation.
