To photometrists....

We have posted AIP4Win version 2.1.9.beta on the 
http://www.willbell.com/aip4win/AIP.htm.

This beta test version incorporates several changes in the 
photomentry tools. In previous versions, the photometry

What happens in 2.1.9.beta is that the tool now get the exposure
time from the image providing that information is properly
formatted in the FITS header. If not found in the FITS header,

In addition, the output now lists the exposure time for each 
image. In the past we had assumed that nobody would 
change exposure times in the middle an image sequence; 
however, we now you can do this if you want to and the 
exposure will be reflected in the output file.

Photometry "sticky," so when you start the tool, you should 
get back the report formats that were active the last time 
you used the tool. 

We have also resolved an issue with the calibration checkbox. 
Photometry *after* you selected the images, the first image 
had already been loaded and therefore could therefore not be 
calibrated. This produced a small difference in results for the 
first image in a sequence, but not in subsequent images,
which were properly calibrated as they were loaded.

In 2.1.9.beta, if calibration is not selected, a messagebox 
pops up and asks whether you want to calibrate the images.
Clicking "yes" checks the box. We have also reversed the 
positions of the checkbox and the button so it is harder to 
forget to check the box if you wish to perform autocalibration 
on loading.

Please note that this is a beta release, and although it has
been tested carefully, it may nevertheless contain residual
bugs. Please report these to us at aip4win

Aside from these changes, 2.1.9.beta incorporates a new library 
for digital camera raw file support that includes just about every 
raw file format known, including the Adobe Digital Negative 
(DNG) format, an industry standard that we hope camera 
manufacturers will adopt. 

We anticipate releasing version 2.1.10 as soon as all of the
changes implemented in 2.1.9.beta have been fully tested.
