Calcmar V3.1 e - Psion 3a/c shareware


Principle

The software calculate hight and low waters of the reference
station to which the selected station is subordinated and moon
aspects at these times.
Then tidal differences of the selected station are applied.
Water dephts at intermediate times are approximated by a square
sine curve.
The moon aspect allows you to predict the night visibility and to
estimate currents strengh in keeping with spring tides (full or new
moon) or neap tides (first or last quater).


Performance

Original data are made up of 24 reference stations and
1201 subordinate stations of Atlantic Coast of North America.

A  station research needs a 1 minute delay by 250 stations
included in database file. So, keeps only stations you need.
Hight and low waters calculation needs a 50 seconds delay.
Screen refreshing needs a 20 seconds delay.


Data updating

CALCMADB alias allows you to update data.
Avoid too many updating on Flash SSD.

Best warranty of up-to-date harmonic constituents is obtained
with hydrographic authorities of concerned countries.
Especially IHO data updating is'nt sure.

Tidal differences (RATTACHE.DBF) may be obtained in "Tide Tables"
published by International Marine

Europe and West Coast of Africa data are available in the french
version of Calcmar V3.1

I can provide data for all the world but without updating warranty.


New stations data entry

Sa, Q1, O1, K1, N2, M2, MN4, M4, MS4 harmonic constituents are
needed to entry a new reference station in CONSHARM.DBF.
It's necessary to also entry it in RATTACHE.DBF even without
subordinate stations. In this case, tidal differences must be null.

See previous item for data sources.


Installation

The different files must be copied on the same logic unit X
(A or B or  M) in this way:
X:\APP\CALCM31e.OPA
X:\APP\CALCMADB.ALS
X:\APP\CALCMAR\COEFF.ODB
X:\APP\CALCMAR\CONSHARM.DBF
X:\APP\CALCMAR\RATTACHE.DBF
X:\APP\CALCMAR\CURSEUR.PIC
X:\APP\CALCMAR\LUNES.PIC
X:\APP\CALCMAR\CALCMAR.PIC
X:\APP\CALCMAR\CALCMA1e.RSC
X:\APP\CALCMAR\CALCMA2e.RSC
X:\APP\CALCMAR\CALCMA3e.RSC

The for latest files are optional. They are introduction screen and
help files.

CALCM31e.OPA and CALCMADB.ALS icons must be installed.


Program updating

From a version before 3.0
Please note your added data before. You'll have to add them after updating.
Heights data are now in feet (x1000).
Erase old version files and icons by the new one
Erase CALCMAR.INI You must initialize again the program. If you are
a registered user, you need your registration code. If you don't remember it,
I can provide it.

From version 3.0
Erase old version files and icons by the new one

Set up

The software opens a new subdirectory Y:\CALCMAR on the logic
unit Y specified by the user. A  RAM unit is better. There is the
CALCMAR.INI file in this subdirectory. It contains the registration
informations, preferences and latest calculated values.

WARNING ! Erasing this file needs to register again the
code if your are a registered user.


Registration

This software is a shareware. It don't work without registration for
a later date than October 31, 1998.

Registration screen appears while the shareware is'nt registered.


Responsability

The author don't accept any responsability in consequences of this
program's use. He calls to you that official tides tables published by
hydrographc authorities offer best warranty of precision and that
the skipper must include a clearance in his calculation.
