fitsdisp
Display FITS metadata
Description
fitsdisp(
displays metadata for all
the Header/Data Units (HDUs) in the specified FITS file.filename
)
fitsdisp(
specifies options using one or more name-value arguments. For example,
filename
,Name=Value
)fitsdisp(filename,Mode="full")
displays all HDU keywords.
Examples
Display Metadata for All HDUs

Input Arguments
filename
— Name of FITS file
string scalar | character vector
Name of FITS file, specified as a string scalar or character vector.
Example: "myFile.fits"
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: fitsdisp("myFile.fits",Mode="min")
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: fitsdisp("myFile.fits","Mode","min")
Index
— HDUs to display
positive integer scalar | row vector of positive integers
HDUs to display, specified as a positive integer scalar or row vector of positive integers.
Example: Index=1
Example: Index=[2 3]
Data Types: double
Mode
— Display type
"standard"
(default) | "min"
| "full"
Display type, specified as "standard"
,
"min"
, or "full"
.
"standard"
— Display standard keywords."min"
— Display only types and sizes."full"
— Display all keywords.
Data Types: string
| char
Version History
Introduced in R2012a
