E-MAP, Continuum data not supported.
ANALYSE, MAP command. The current index contains continuum drifts, instead of spectra. MAP only works on spectral line data.

E-MAP, Incoherent offset type for scan <Integer>
ANALYSE, MAP command. The current index contains offsets in different coordinate systems.
User action : drop the faulty spectrum from the index.

E-MAP, Index is empty
ANALYSE, MAP command. No map can be plotted.
User action : Define the current index using the FIND command and retry.

E-MAP, Map too large, <Integer> by <Integer>
I-MAP, Check tolerance (SET MATCH) please
ANALYSE, MAP command. The number of cells in the map defined by the index is too large, so that the spectra would be too small. This may be due to rounding errors in the offsets which lead to an anomalously small cell size.
User action : increase the tolerance in SET MATCH by a factor 2. If the error persists, give explicitly the cell size (/CELL option) If this does not help either, verify that the index does correspond to a single source.

E-MAP, Mode X and Y must be fixed
ANALYSE, MAP command. The X and/or Y axis has an automatic scaling enable, and must have a fixed scale.
User action : Specify a fixed scale for all spectra using the SET MODE command, and retry the MAP command.

E-MAP, No input file connected
ANALYSE, MAP command. No input file is opened.
User action : Open the input file, define the current index using the FIND command and retry the MAP command.

E-METHOD, Cannot open HFS description file.
E-METHOD, Error reading HFS description file.
ANALYSE, METHOD command with argument HFS. The Hyperfine structure of the line to be fitted could not be read from the specified file.
User action : Check the file name or content for proper format. See HELP METHOD.

E-METHOD, Too many HFS components
ANALYSE, METHOD command with argument HFS. The hyperfine structure specified has too many components.
User action : Relinking the program is required to increase this parameter. Contact the authors and supply the number of components required. You may solve adequately your problem by suppressing from the description the weakest components if they are negligible.

E-MOBS, Observation to be modified was not found
LAS, Input/Output routines, UPDATE or KEEP commands. The user attempted to modify an unexistant observation.

E-MOBS, Non-standard obs. block <Integer>
LAS, Input/Output routines, UPDATE or KEEP commands. The input/output file contains an invalid data block because it has been corrupted.
User action : see ``Recovering Corrupted Data Files'', and notify your system manager because this is usually due to hardware errors.

I-MODIFY, Beam efficiency set to <Real>
ANALYSE, MODIFY command. The beam efficiency value was previously undefined and has been set to the specified value. No scaling occured.

E-MODIFY, Invalid beam efficiency <Real>
ANALYSE, MODIFY command. The beam efficiency value must be between 0 and the forward efficiency (less than 1).

E-MODIFY, MODIFY POSITION not supported for this type of projection ANALYSE, MODIFY command. Offsets relative to the new central position cannot be computed in the present coordinate or projection system
User action : Submit an SPR, specifying the projection used. We will try to implement it properly in future releases.

I-MODIFY, Offsets set to <String>
ANALYSE, MODIFY OFFSETS command. Information message.

I-MODIFY, Reference channel set to <Real>
ANALYSE, MODIFY RECENTER command, information message.

I-MODIFY, Image frequency set to <Real>
ANALYSE, MODIFY IMAGE command, information message.

W-MODIFY, Unknown projection type, Radio projection assumed
ANALYSE, MODIFY command. Offsets relative to the new central position were in a unknown projection system.

F-MOX, Output file not opened
LAS, Input/Output routines. A WRITE operation was attempted before any output file was opened.
User action : open output file and retry the aborted command.

F-MOX, Read error block <Integer>
LAS, Input/Output routines. A WRITE operation failed because the output file index could not be read correctly.
User action : see ``Recovering Corrupted Data Files'' and notify your system manager.

F-MOX, Write error block <Integer>
LAS, Input/Output routines. A WRITE operation failed because the output file index could not be written correctly.
User action : see ``Recovering Corrupted Data Files'' and notify your system manager.

E-MOX, Wrong index address <Integer>
LAS, Input/Output routines. A WRITE operation failed because the index address is incorrect. This may be due to update a spectrum which does not exist in the output file.
User action : if the error was caused by an UPDATE or KEEP command, try a WRITE command instead ; else, or if the error persists, submit an SPR.
