pyspi.utils.response.spi_frame.j2000_to_spi(j2000_frame, spi_coord)

Transform icrs frame to SPI frame

pyspi.utils.response.spi_frame.spi_to_j2000(spi_coord, j2000_frame)

Transform spi fram to ICRS frame

pyspi.utils.response.spi_frame.transform_icrs_to_spi(ra_icrs, dec_icrs, sc_matrix)

Calculates lon, lat in spi frame for given ra, dec in ICRS frame and given sc_matrix (sc_matrix pointing dependent)

Parameters

• ra_icrs – Ra in ICRS in degree

• dec_icrs – Dec in ICRS in degree

• sc_matrix – sc Matrix that gives orientation of SPI in ICRS frame

Returns

lon, lat in spi frame

pyspi.utils.response.spi_frame.transform_spi_to_icrs(az_spi, zen_spi, sc_matrix)

Calculates lon, lat in spi frame for given ra, dec in ICRS frame and given sc_matrix (sc_matrix pointing dependent)

Parameters

• az_spi – azimuth in SPI coord system in degree

• zen_spi – zenit in SPI coord system in degree

• sc_matrix – sc Matrix that gives orientation of SPI in ICRS frame

Returns

ra, dex in ICRS in deg
