The format of file "mpcreport.txt"corresponds to the standard
accepted by Minor Planets Centre (MPC). The recordings with the data contain:
for 1-5 bytes is number of a numbered minor planet,
6-12 - a designation unnumbered minor planet,
16-19 – year,
21-22 – month,
24-31 – day,
33-44 – right ascension,
45-56 – declination,
66-69 – star magnitude,
78-80 – code of observatory.
Positions 1-80 file "mpcreportiz.txt"are similar to positions
of file "mpcreport.txt".
83-95 – errors of unit weight,
97-100 – number of a reference stars,
102-106 – number of stars in frames from a catalogue,
108-120 – limits of residuals,
123 – order of solution,
125-127 – number of a plate const.,
129-137 – minimum and maximum magnitudes of a reference stars,
139-144 – time of exposition (hundredths of second),
146-166 – Mx, My,
168-173 – g,
175-181 – q ,
182+ name of a file.
The file "izmccd.log" has the following structure:
Positions 1-6 contain a special tag.
If this tag is " 1 0 ", this record contains results of
measurements of an image of object (approximation by "PSF"),
8-11 – year,
13-14 – month,
16-17 – day,
19-20 – hour,
22-23 – minute,
25-26 – second,
28-33 – time of exposition (hundredths of second),
35-44 – coordinate X of object (pixels),
46-55 – Y,
57-66 – error in
X (pixels), for first star in a multicentric image,
for subsequent it is error in
![](./izmccdEng.files/image028.gif)
(distance between first star in the
image and this),
68-77 – error in
Y for first, and error in
![](./izmccdEng.files/image030.gif)
(positional angle) (radian) for subsequent,
79-88 – error at approximation of the image of object by "PSF",
90-92 – zero-based index of this object in the multicentric image,
94-96 – number of objects in the multicentric image,
98-101 – index of this object in the frame,
103 – if there is 0, this object was measured with the preassigned value

(See section "
Basic
algorithms of program"about sense of parameter), if 1
![](./izmccdEng.files/image033.gif)
was calculated as variable,
105 – if there are 1, there was used elliptic "PSF",
107 – if there are 1, A and B were common for the multicentric images, 0
- separate,
109 – if 1, the displacement of the aperture was made, 0 - was not made,
111 – if 1, profile of Lorenz was used, 0 - Moffat,
