The filter code '&' is:
"r" for the filter no 1, 630.0 nm
"s"
"t"
"u"
"v"
"g" for the filter no 2, 577.7 nm
"h"
"i"
"j"
"k"
"b" for the filter no 3, 427.8 nm
"c"
"d"
"e"
"f"
The explanation of this is. The ACC2 program creates a
new directory for each hour. Each image is stored in
one file. Normally "r" is the filter code for the 630.0 nm
filter no 1. However, if more than 256 (00 to FF Hex) images
for filter no 1 are stored at each directory, the code for
filter no 1 switches to "s". If more than 512 images are stored
for filter no 1 in this hour, the code switches to "t", etc. .
As an example the images stored at data\images\971124\14
directory is:
97112414.00R
97112414.00G
97112414.01R
97112414.01G
97112414.02R
97112414.02G
97112414.03R
97112414.03G
97112414.04R
Windows explorer can be used to show the on line occurrence of
new data files at current directory.
When the ACC2 program is stopped and then started again the
image counter (%%) automatically continue after the last image
file written to harddisk. No image files are overwritten. This
information is stored in the rcount.dat, gcount.dat and
bcount.dat files in each directory.
