tem Description

F
irst image no. Image number of first image. Range is 1 through 999.
N
o. of images Number of images to be collected. Range is 1 through 999.
E
xp. time Exposure time in seconds. In DOSE mode, the actual time
may be different from the desired exposure time.
O
scillations Number of ϕ−oscillations per image. One oscillation is
stronlgy recommended for exposure times < 15 min.
∆ϕper image ϕ movement per image.
S
tarting ϕϕposition to start data collection.
D
istance Distance crystal to detector.

For convenience, the program calculates the maximum resolution possible from the chose
n
distance and the chosen scan mode (image plate diameter).
The image names are created according to the following convention:
directory / root_TYPE_XXX.extension
− TYPE is:
not used in Single Data Set mode e.g. /images/zeo_001.mar1200
1, 2, 3 or 4 in Multiple Data Set mode e.g. /images/zeo_1_001.mar1200
INDEX in Index Crystal mode e.g. /images/zeo_INDEX_001.mar1200
A or B in MAD Data mode e.g. /images/zeo_A_001.mar1200
−
XXX is a three digit image number like 027,
− extension is:mar1200, mar1600, mar1800, mar2000, mar2300, mar2400, mar3000 or
mar345 for Output format "mar345", depending on the Scan mode chosen.
In Index Crystal mode "First image number" is replaced by "
ϕ increment" (see above
).
The starting image will always be 001 and the following images will have numbers that will b
e
calculated from their ϕ−position relative to image number 001 according to:
XXX=i*
ϕ increment / ∆ϕ+ 1 (i=0,1,2,3...)
e.g. with
ϕ increment = 90.0 and ∆ϕ= 2.0, XXX = 1, 46, 91, 136, etc.
