fromaste(fmlolog, backendlog, antennalog=None, byteorder='<')[source]#

Read logging data of ASTE and merge them into a FITS object.

Parameters:

  • fmlolog (str) – File name of FMLO logging.

  • backendlog (str) – File name of backend logging.

  • antennalog (str) – File name of antenna logging (optional).

  • byteorder (str) – format string that represents byte order of the backendlog. Default is ‘<’ (little-endian). If the data in the returned FITS seems to be wrong, try to spacify ‘>’ (big-endian).

Returns:

HDU list containing the merged data.

Return type:

hdus (HDUlist)

fromnro45m(fmlolog, backendlog, antennalog=None, byteorder='<')[source]#

Read logging data of NRO45m and merge them into a FITS object.

Parameters:

  • fmlolog (str) – File name of FMLO logging.

  • backendlog (str) – File name of backend logging.

  • antennalog (str) – File name of antenna logging (optional).

  • byteorder (str) – format string that represents byte order of the backendlog. Default is ‘<’ (little-endian). If the data in the returned FITS seems to be wrong, try to spacify ‘>’ (big-endian).

Returns:

HDU list containing the merged data.

Return type:

hdus (HDUlist)

getarray(fitsname, arrayid, scantype, offsetsec=0.0, *, computeam=True, ignore_antennalog=False)[source]#

Create a modulated array from a FMFITS.

Parameters:

  • fitsname (str) – File name of a FMFITS.

  • arrayid (str) – An array ID with which the output fmarray is created.

  • scantype (str) – A scan type with which the output fmarray is created.

  • offsetsec (float, optional) – A float value of FM offset time in units of sec.

  • computeam (bool, optional) – If True, atmospheric model is computed. Default is True.

  • ignore_antennalog (bool, optional) – Whether ignoring antenna log. Default is False.

Returns:

A modulated array of the spacified arrayid and scantype.

Return type:

array (xarray.DataArray)
