Improved drawing of some Monte Carlo particle tracks
having no MIMPs. Now also the data from mtra->mtcp
and mtra->leng are used.
This can have an unwanted side effect: too many
low-energy photons are drawn. To reduce their number,
a cut on the momentum of neutral Monte Carlo particles
can be done by command
which sets this cut to 0.01 GeV.
Charged particle tracks are drawn without using this cut.

New command DIOTR shows number of OTR single layers for a given superlayer.
Number of passes of OTR single layers is shown
for a straight track coming from target (x=y=z=0).
Parameters of command:
- SL - superlayer name (can be generic, e.g. PC or ALL)
If SL=ALL then all OTR superlayer are selected.
If SL=PC then all PC superlayer are selected.
- lay - stereolayer (use 0 for all stereolayers)
- Usemask - non-zero if channel mask should be used (default is non-zero)
(=1 - count good cells)
(=2 - count bad cells)
- Countcell - non-zero if cells should be counted (default is single layers)
Recommended sequence of Prism commands:
view 0 -n
sty stereo=y sens=y head=n
frame -r -n
draw; diotr MC01 3 1 0; dilay MC01 3

DICELL now works also for
not only for Wax interface to OTR channel status (thanks to D.Goloubkov).

Introduced option to request continuation of RSEGs
to some Z coordinate.
After STYLE ZCONT=-5, RSEGs will be continued as straight
lines to Z = -5 cm. To switch off this behaviour,
use large negative number, e.g. STYLE ZCONT=-900.
Segments are not continued through magnet.

SLT information is displayed if style slt=y is on.
SLT information can be used to determine
the cross-section plane for displaying OTR cells,
e.g.: DICELL -HS TRIGGER=0 TRACK=1
Output of STYLE -L changed, names of parameters updated.

Reconstructed segments can be picked by /DI/PICK RSEG.
Additional information is displayed with picking GEDE.
ITR hits are drawn with smaller circles.
Hit color is green for top chambers,
and violet for bottom chambers (thanks to T.Zeuner).
View command does not reset the frame
if view is changed from 1 (ZX) and 7 (ZU) or 8 (ZV).

After style rtrhit=n RSEGs are drawn not by RHITs,
but by the segment endpoints.
Additions in DICELL command:
- show in a special color those cells which have been flagged
as correlated noise by Maarten's noise reduction
+ channels at missing FED.
- Fix in selection of MTRA

Command FRAME now allows to move window
Up, Down, Left or righT with options -U, -D, -L, or -T
(unfortunately, -R was already used for Reset).
Factor can be specified:
e.g. FACTOR=0.5 means to move only by half of screen.

New dicell command for OTR cut view with capability of displaying
cell status, hits, and some additional information.
Introduced new Prism colours:
CEH - to display cells with HITB,
CER - to display cells with RHIT.
Introduced commands PILINE to draw line, PIBOX to draw box.
When Prism is initialized, it looks for file prism_init.kumac
in the current directory, and if found, executes commands from it.

New dicell for OTR cut view with capability of displaying cell status,
hits, and some additional information.
This is a preliminary version which will be changed further.
Reconstructed track trajectories can now also be displayed if only the
information in RTRA is available. This is useful eg for application
on reconstruction output where the RHIT table is usually
not at hand. It is mainly intended for investigating reconstruction vertex
assignments. This feature is automatically invoked for charged tracks when
no RHIT table exists but the hit count in RTRA is non-zero.
Note however that - due to multiple scattering - extrapolation of the trajectory
from the first-point information alone is limited in presision, which becomes
visible for momenta below ~5 GeV/c. Note also that the track length is
not known in RTRA, and the endpoint is selected simply by guesswork
based on the hit counts.
The default line thickness for rendering of MTRAs and RTRAs
has been reduced for better resolution especially when judging vertex reconstruction.
If you prefer the old style with thicker & more placative lines, you
can get it back with the command
display/style widrt=6 widmt=6
It is possible to restrict the display of reconstructed tracks to those
belonging to a special vertex (eg. the second one) with
Submitted for ARTE-02-08-r2,
Display of reconstructed neutral particles (recognized by rtra->fit
= 6) has been introduced. It is coupled to the display/style
options rtra and neut, both of which must be active.
The assumed identity of the reconstructed particle according to a simple-minded
particle identification is displayed when the display/style options
rtra and type are both active.
A bug in the pick command has been fixed.
The style options rpnt, rccl, gcal have been introduced, which
switch the display of these objects.

Some special outer tracker drawing commands dicell (displays a cut
view of OTR honeycomb cells) and dilay ( displays GEDE volumes with
color according to sector, both by A. Lanyov) have been added.
Display of target & background rates for real data (using routines
by A. Gellrich) introduced (revoked later because of problems).

di1rseg switched to new trajectory rendering scheme, ignores kill-flagged
markers introduced in ditraj
wobbles bug fixed in di1rtra
A unified trajectory rendering scheme has been introduced and is for the
time being used for MTRAs. A long standing bug which prevented the display
of neutral Monte Carlo particles was fixed. The display of ECAL hits and
clusters on the lambda-phi view (11) was enabled.
Submitted for ARTE-02-05-r3,
A RICH event display has been introduced which was provided by D. Dujmic
(thanks!). For this the new view 11 (lambda/phi angles) has been added.
An ECAL cluster display provided by A. Somov (thanks!) has been added.
RSEGs and ECAL cells can also be displayed on this view.
In the command syntax, the present Arte table nomenclature should now
be used everywhere, eg you should use "pick mtra" instead of "pick mc"
etc. Sorry for any inconvenience because of these changes, but I am sure
that this way, the commands are easier to handle in the long run.
Submitted for ARTE-02-05-r2,
Adaption to Arte-02. A frame stack which recalls the last five frame settings
has been introduced (command: display/frame -b). A bug the reconstructed
vertices display was fixed.
The references to Arte table names in commands and parameters have been
streamlined and adjusted to the current Arte nomenclature. All occurences
of the old terms MC, RC, PLANE etc should (hopefully) have
been replaced by MTRA, RTRA, GEDE etc. Sorry for inconveniences
if you have been accustomed to the old names, but in the long run the new
nomenclature is clearly more consistent.
