uvputhd - Allows user to alter values of header variables in uv dataset

DESCRIPTION

UVPUTHD allows the user to change the values of uv variables in a uv dataset. All occurances of the variable are changed to the new value. If the variable is an array, all new values must be entered in sequential order. If the user desires to set all members of an array to a single value, only one value needs to be entered. Values can also be inserted from a time ordered table. Note: PUTHD must be used to use the uv override principle, but can only be used for single items, i.e. uv variables which are not an array.  

PARAMETERS

vis
Name of the input MIRIAD dataset. Only one dataset is allowed. No default.
hdvar
Name of header variable to be changed. Refer to user manual or run VARLIST to see the selection of allowed variable names. Although one is allowed to make up new uv variables, this is not a recommended practice. No default.
type
Type of variable, either integer (i),real (r), double precision (d), or ascii (a). Unused if variable already exists in the data file. CAVEAT: Tables do not support ascii types yet. No Default.
length
Length of array of variable values. Unused if variable already exists in data file or table is specified, else set to 1.
varval
New values of header variable - if the variable is an array all values must be specified or will assume one value for all. If you want values that change with time, you must use the table= keyword instead. No default.
table
Name of the table that lists time (fractional days since time0) in column 1, and the values of the array in columns 2 through LENGTH+1. Values are simply inserted as soon as the time has passed, no interpolation is performed. CAVEAT: do not use array variables with tables, and type=ascii cannot be used either. No default.
time0
Offset time as applied to the times in column 1 of the table for tabular input. Legal formats as defined in subroutine DAYJUL, of which the ISO standard "ccyy-mm-dd[Thh[:mm[:ss.s]]]" is to be preferred. Default: not used, in which case the offset is 0, in which case fractional days are really Julian Days.
out
Name of the output dataset. No default.
