	IH DATABASE

DATABASE ADDITION The Database is an extension of the Intelligent Handset and as many of you know it has been a long time coming. In order to achieve a large number of objects the available datafiles have had to be compressed (some typed in) and coded using BASIC programmes specially developed; datafile compilation and internal handling have had to be written and debugged before any work on menu screen presentation, filtering and GOTO operations were coded. This has all been done including the coding for secondary catalogues. Any code changes result in a new memory chip being required. Royalty payments for using the modern Revised NGC/IC Project database means that there is an update charge of £65 (incl VAT).

DATABASE FEATURES The database adds catalogues of objects into the Intelligent Handset which form the basis of observing sessions. The total storage capacity is about 20,000 objects into a FLASH memory chip of size 4M bit. It is possible for the user to fill the data memory just with the catalogues that are of interest. Some catalogues (the secondary catalogues) require full data provided in objects from other catalogues. A maximum of 20 catalogues can be loaded up to the maximum size. Up to 16 sectors can be programmed, the sizes of the individual catalogues are given below. There is an erase procedure which wipes the lot and a formatting procedure so the catalogues of interest can be included, and changed later. Any catalogue can be added in any order! If a catalogue is missed out then it is not a problem - the missing data is just ignored. It is the intention to add further catalogues such as one for Double stars, Variable stars. Contact AWR if you would like a specific catalogue!

The menu structure for selecting objects is quite simple by using the function buttons, selecting the catalogue, the object by its number or by selecting with user set magnitude limits and type selections. Full information about the object is given.

CATALOGUE SELECTIONS The following database files can be downloaded and installed by the User. Each item is compacted although each record is an individual object. Text files are available for all the datafiles for checking purposes. An extra word on the catalogues.

The PRIMARY catalogues below 16 contain all the data about an object (number, position, magnitude, size, type, constellation). If the proper names are required then you need catalogue 32 or 33. Miscellaneous catalogues are in the range 9 to 15 and contain all the data and an 8 character name to be displayed. The SECONDARY catalogues in the range 16 to 31 are index lists and contain very limited extra information and fetch the relevant primary catalogue information.

USING THE MENU'S

COORD is the route to entering a coordinate from the screen.
CAT selects catalogues, objects and filters (SEE NEXT SCREEN BELOW)
PLNT will allow finding the planets. Not much code space is left at present. AB will be working on it!
MREV is Meridian Flip for German Equatorial Mountings if the function is enabled (Factory menu).

Selecting CAT -

CATLG changes the selected catalogue by scrolling through the list of those loaded.
OBJ allows number entry from the keyboard (the object number) followed by (E) or STEP into the first entry of the catalogue.
NEAR toggles a flag to fix the object search to the same constellation. NEAR has been selected and is shown in the above screen in red.

When the object has been selected the object information is presented.The data screen shows full information about the object contains the object number, type(s), magnitude, size, catalogue RA & DEC positions, constellation and proper name if present. A large quantity of objects have multiple types and are presented on the screen as such. On pressing GOTO you will be told if it is outside your possible viewing envelope bounded by HORIZ MAXDEC MAX-HA. (The artificial Horizon, maximum Declination and maximum Hour Angle).

GOTO performs the GOTO with precessed coordinates. When the telescope has arrived the menu line changes to SYNC to do a calibration point when you have centred the object.
ADD adds the precessed object coordinates into the list for use with PREV function. A list can be prepared before hand for the observing session.
NEXT selects the next object in the selected catalogue that complies with the filter specification.
STEP selects the next record number irrespective of the filters but in the selected catalogue. The Modern NGC objects are non-consecutivly numbered. If you are in the NGC then it will step into the modern catalogue (if present) to give a consecutive list of the whole catalogue. It will continue thereafter in the main catalogue. The Miscellaneous objects have their own identification, non-sequential.
The (C) button takes you back to the CATALOG screen for selecting the next object number.

FILTERING Selecting FILTR -

Finding the objects in a 20,000 data file is quite difficult so we have added filters so you can select by catalogue and object type (up to 16 object types) with a selectable magnitude limit. Any one or combinations of object types are allowed with a separate magnitude limit and possibly fixed to the same constellation. The arrow keys move the cursor to the letter (object type) to be included, it is curently on the M. The example above shows (P) Planetary Nebulae (r) reflection Nebulae and (O) Globular Clusters have been selected.
MAG scrolls the limit between +8, +10, +12, +14 and none.
ALL puts on ALL object types.

DATABASE MAINTENANCE Advanced users may wish to change which catalogues are stored or add to the ones already present. To perform this you must have the IH-PC serial lead and a terminal programme to transfer the files. Suitable programmes are HYPERLINK (Windows) and .... (Apple Mac). You can download the catalogues from the IH Database Download Page.
