The following parameter(s) have to be specified for the entire map:
APERTURE (for PHT-P only): one aperture for the complete
sequence of measurements
FILTER: specify central wavelength of each filter requested
For each point of the sparse map the observer specifies the following parameters:
POINT OR EXTENDED SOURCE: define type of source; this
parameter defines whether the EXPECTED SOURCE FLUX is given in Jy or
MJy
EXPECTED SOURCE FLUX: best available estimate of source flux
(see Sect. 6.2)
UNCERTAINTY IN SOURCE FLUX: uncertainty of source flux estimate
MAXIMUM BACKGROUND FLUX: expected background flux at source
position including all components (see Sect. 6.2)
INTEGRATION TIME or S/N: integration
time requested for each position or, alternatively, the required
signal-to-noise ratio
