DIMM Release Notes, Version 2.91

Version 2.91 was released on 26-February-2015.

This release added acquisition logging info:

• FITS dump of acquisition image including vmag, target RA/DEC, distance from LBT, exposure time
• image stats for acquisition image
• calculated background of peaks
• number of centroids found in each step

Changed the centroiding to calculate the background using all stars not in 5x5 pixels around the peak (it was using a 5-pixel swath through the 30x30 image).

Fixed crash on file rollover time since the log file was not cleaning up correctly for all types of log messages.
