| 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. |
|
| 2026-04-21: The
BRG_OFF is now without Ks for T1T4. |
|
|
|
| 2026-04-27:
Some mistakes! OC1_3, NB1550, and MBK3, and J2H2K2 information is corrected. |
