| Update History: | ||||||||||||
| 2016-10-10: Default order-sorting filter for VPHJ is changed from OC_ZJ to HOLE+CSL. This mode has been effective since the October observations. | ||||||||||||
| 2016-11-15: The alias for VPH filters has changed to keep their consistency with grism name. e.g., DEF_VPHJ --> DEF_VPH_J etc. | ||||||||||||
| 2016-11-15: TheNB filters used with the VPH_H grism with the window imaging has changed from Fe2 to NB119, as the sky for Fe2 is too bright. | ||||||||||||
| 2020-06-30: VPH-Y and R1300 Grisms were retired in 2020. Instead, LS_J and LS_H Grisms were installed in 2020. All the related aliases were updated. | ||||||||||||
| 2020-09-17: The filter for LS_J has changed from CSLM to OC_ZJ to suppress the ghost. | ||||||||||||
| 2023-2-5: VPH-Y is back, VPH-J/H are removed. A confusion on VPH_HK and VPH_K are cleared now. | ||||||||||||
| 2023-02-05: The retirement of K-cont and ND were reflected to the table. | ||||||||||||
| 2024-03-05: removed remaining VPHJ/H part. Editted VPH_K part following the change of the definition. Added VB_K-related definition. Removed th BP-adding definition and put the note for it. | ||||||||||||
| 2025-08-08: IMMBJ2, IMMBH2, IMMBK2, BRG_ON, BRG_OFF are added. The defs related to VPHK are all removed due to retire. | ||||||||||||
