log_id¶

Return the string log ID for the info.

The log ID is used to extract certain information from table data.

Returns:

str

Methods Documentation

apply_configuration()[source]¶

Update scanning information with FITS header information.

Updates the scanning information by taking the following keywords from the FITS header:

SCNPATT - The scanning pattern (str)
SCNCRSYS - The scanning coordinate system (str)
SCNAMPXL - The scanning x-elevation scanning amplitude (arcsec)
SCNAMPEL - The scanning elevation scanning amplitude (arcsec)
SCNANGLC - The current scanning angle (degree)
SCNANGLS - The initial scanning angle (degree)
SCNANGLF - The final scanning angle (degree)
SCNDUR - The scan duration (seconds)
SCNITERS - The number of scanning iterations (int)
SCNNSUBS - The number of sub-scans (int)
SCNLEN - The raster scan length (arcsec)
SCNSTEP - The raster scan step size (arcsec)
SCNSTEPS - The number of raster scan steps (int)
SCNCROSS - Whether the scan is cross-scanning (bool)
SCNFQRAT - The Lissajous y/x frequency ratio (float)
SCNPHASE - The Lissajous y/x relative phase (degree)
SCNTOFF - The Lissajous time offset (seconds)
SCNTWAIT - The track relock time window (seconds)
SCNTRKON - Whether tracking is on/off (0/1) (int)

Returns:

None
